    14 Most Popular Legends About Mozart

    Wolfgang Amadeus Mozart is the most mythologized figure in the history of music. No other biography has given rise to as many rumors, legends, detective stories, and fictions.

    Some rumors appeared during Mozart’s lifetime, thanks to his relatives, friends, and acquaintances. Others emerged much later, during the Romantic era at the beginning of the 19th century: the Romantics were inspired by both Mozart’s work, especially the story of Don Giovanni, and his early death. Here, we explain where the various legends about the great composer came from.

    Mozart Was a Child Prodigy Who Began Playing and Composing Music at the Age of Four

    Verdict: This is almost true.

    Mozart was indeed a child prodigy and the most famous one in the history of music. He began playing early and mastered the art remarkably quickly. Leopold Mozart, a legendary music teacher, described his son’s remarkable achievements on the clavier, an early version of the modern piano: “Wolfgangerl learned the Minuet and Trio on January 26, 1761, at half-past nine in the evening, in half an hour, the day before he turned five.”

    Meanwhile, the boy was also learning to play the violin—one of his childhood violins can be seen in Salzburg, in the house where he was born. Immediately after his son’s birth, Leopold Mozart published a textbook, “A Treatise on the Fundamental Principles of Violin Playing” (“Versuch einer gründlichen Violinschule”), which he apparently began to test. At the age of seven, Wolfgang Mozart was already playing the violin for the archbishop, and at eight, he started performing on the organ.

    The earliest surviving manuscripts by Mozart date back to 1764, when the author was also eight years old. Before that, the child’s improvisations and compositions were recorded by his father. According to Leopold’s meticulous notes, Mozart completed his earliest improvisation at the age of five, in April 1761. Less than a year later, he composed his first piece—an Allegro in F major for the clavier. Among the world’s classical composers, only Sergei Prokofiev began composing at such an early age.

    Mozart Was Forced to Practice Music

    Verdict: False.

    Leopold Mozart was a progressive and talented teacher, so he used encouragement rather than punishment. His educational approach required time, patience, and dedication, allowing him to nurture his son’s talent without harsh intervention. He never used corporal punishment on his children. To Wolfgang, his father’s authority was unquestionable—he practically worshipped him, claiming that “after the Lord comes Papa.” In turn, Leopold saw him as a genius.

    Wolfgang amazed his parents so much with his talent that they tended to indulge him. Johann Adolf Hasse, one of the famous composers of the time, even worried: “Let’s just hope the father does not spoil him too much with exaggerated praise.”

    Mozart Quickly Became a Child Star and Performed All Over Europe

    Verdict: True.

    Leopold Mozart was the father of two prodigies: Nannerl, Wolfgang’s older sister, was also a promising performer. Their first tours began in January 1762, when the younger Mozart was six years old and his sister was ten. Although Munich, where they headed, is not far from Salzburg, it was still a real tour. At the court of Maximilian III Joseph, Elector of Bavaria, they spent three weeks.

    Together with his sister, Wolfgang toured all the musical capitals of Europe. Just six months after the triumph in Munich, their father took the children to Vienna. At one stop, they gave their first public concert, and in Vienna, a whole series of performances awaited them: at the court of Maria Theresa, in aristocratic salons, and in the homes of foreign ambassadors. It was then that they received an invitation to perform in Versailles.

    In early summer 1763, the whole family set off on a three-year tour of Europe: Munich, Augsburg, Ulm, Ludwigsburg, Bruchsal, Mannheim, Schwetzingen, Frankfurt am Main, Koblenz, Bonn, Cologne, Aachen, Brussels, and finally, Paris and Versailles. These were just the cities where they gave concerts. The main goal of the journey was an audience with Louis XV in Versailles. The next destination was London. George III was so impressed by the performance that he wished to hear the prodigies again at celebrations for another anniversary of his ascension to the throne.

    After almost a year in England, their travels continued: Canterbury, Calais, Lille, Ghent, Antwerp, The Hague, Amsterdam, Utrecht, Antwerp again, Brussels, Paris, Versailles, Dijon, Lyon, Geneva, Lausanne, Bern, Zurich, Donaueschingen, and finally, Munich and Salzburg once more. Wolfgangerl returned home as a famous musician who had performed before kings. On the eve of his fourteenth birthday, the family went to Italy. The second and third Italian journeys, undertaken in 1771 and 1772 by the male members of the Mozart family, were triumphant. Europe was conquered, and with it, the entire musical world.

    Mozart Was Supported by Kings from Childhood

    Verdict: True.

    During his European tours, Mozart became familiar with court life, and later, the Viennese court became his place of work. The pinnacle of his court career can be considered his audience with Pope Clement XIV at the Vatican. Mozart was 14 years old, and the Pope had already inducted him into the Order of the Golden Spur.

    As an adult, Mozart continued to associate with aristocrats and monarchs he had met in his childhood. Sometimes, his independent character and sharp tongue could cause trouble. A famous example is the dialogue between the composer and his main patron, Joseph II, at the premiere of The Abduction from the Seraglio (Die Entführung aus dem Serail):

    ORSINI-ROSENBERG: Too many notes, Your Majesty?
    EMPEROR: Exactly. Very well put. Too many notes.
    MOZART: I don’t understand. There are just as many notes, Majesty, as are required. Neither more nor less.

    Mozart Was Considered a Genius, So He Earned a Lot

    Verdict: True.

    Over the years of touring, Mozart managed to earn a lot of money; his family became one of the wealthiest in the provincial Salzburg. At 18, Wolfgang already received an annual salary of 150 gulden as the concertmaster of the court chapel. But this was not his only source of wealth. Admirers, including royalty, regularly presented him with gifts. Typically, these were jewels, which the musician, following the practice of the time, pragmatically “cashed in.” Significant income also came from European productions of his operas and publications. He continued to perform as a virtuoso.

    At the age of 25, Mozart finally moved to Vienna, left his service, and became a freelance artist. Orders kept coming in, and his operas and performances were successful. For four years, he held solo concerts, known as “academies,” for the most distinguished audiences, including the imperial couple. For one of these concerts, he received a fee of nearly 1,600 gulden.

    Like most musicians of the time, Mozart earned not only from performances and theatrical productions but also from lessons—conducting 3–4 lessons daily. The number of students from wealthy, preferably aristocratic, families was a measure of success in the musical world.

    At 30, Mozart was living in Vienna with his family and received a steady annual salary as a court chamber musician at the Viennese court. His only requirement was to provide musical arrangements for balls—a position that was more honorary than laborious. The Austrian Emperor Joseph II commissioned an opera from him, and the King of Prussia, Frederick William II, commissioned six string quartets.

    Mozart was considered a fashionable composer, so people were willing to pay for his work. However, his talent was not universally recognized. His contemporaries—Antonio Salieri, Domenico Cimarosa, and Vicente Martín y Soler—received far more recognition during their lifetimes. Mozart believed he deserved more and was pleased to quote in a letter to his father the praise of a nobleman: “Such people appear only once every 100 years.”

    But He Was Bad with Money and Lived Very Poorly

    Verdict: Partially True.

    The extreme poverty of the composer is a myth. It was created by Constanze Mozart, who sought help from her husband’s influential acquaintances after his death. The debts were paid off fairly quickly, which means they were not very large.

    However, Mozart indeed was not very skilled with money, although he constantly tried to convince his father otherwise. He spent all he earned on renting expensive housing in central Vienna, maintaining servants and his own carriage, entertaining guests, clothes for himself and his beloved wife, and regular grooming to meet court standards. He got married in Vienna’s main cathedral, St. Stephen’s. In the last years of the composer’s life, Constanze frequented an expensive resort, which added to the expenses. It is difficult to say whether the treatment was a necessity or just as fashionable as the expensive clothes.

    Mozart could not control not only his expenses but also his income. He clearly missed out on royalties from many theaters staging his operas. Copyright laws were poorly enforced at the time, and Mozart neither liked nor was able to chase down debtors. He loved and knew how to compose and perform music—and he spent all his time on it. In the last four years of his life, his financial situation worsened. But this was not Mozart’s fault: Austria entered a war, which led to an economic crisis. Patrons became less generous, and the composer did not live to see better times.

    Mozart Stole Other People’s Ideas

    Verdict: This is not true.

    Originality became the main virtue of music only after Mozart’s death: the motto of the Romantic era was the idea of inventing musical material. In Mozart’s time, the concept of one’s own and others’ ideas, or plagiarism, had not yet been formed. Creativity was based on working with models—these could be a genre, style, or even a musical theme composed by someone else. This is why the historical style of that era is now more recognizable than the individual styles of specific authors.

    Mozart worked with a vast amount of what he heard and played; borrowing for him was a dialogue with other composers and other compositions. Today, we do not always catch the wit of this dialogue. Many authors important to Mozart have been forgotten, and his music has become a symbol that sums up the entire era.

    Mozart Collected Wigs

    Verdict: This is more likely not true.

    At that time, wigs were an integral part of the appearance of a secular person, although Mozart himself wore them only on special occasions and was often depicted in portraits with his own well-styled hair. He mentions the burdensome expenses on barbers only in passing in some letters. There are also recollections from friends about his dandyism and detailed descriptions of fashionable clothing in his letters. However, nothing is known about Mozart’s passion for collecting wigs.

    Mozart Had Many Women

    Verdict: This is more likely not true.

    We cannot judge this accurately because the only sources of information are Mozart’s letters—mainly to his father. 27-year-old Wolfgang Amadeus wrote to Leopold:

    I can in no way live like most young men today. Firstly, I am too devoted to religion; secondly, I have too much love for my neighbor to seduce an innocent girl; and thirdly, I feel too much horror and disgust, fear and dread of diseases, and too much love for my health to get involved with promiscuous women. And I can swear that, up to now, I have not had dealings of this kind with any woman—because if it had happened, I would not have hidden it from you…

    However, it is possible that Mozart was not entirely honest with his father, knowing his strict religious and moral principles. Before leaving Salzburg, he was under close parental supervision, and, breaking free from this care, he immediately fell in love.

    Judging by Mozart’s letters, the singer Aloysia Weber, whom he planned to marry, hoped to use him to obtain lucrative contracts in Italy. Wanting to help his beloved’s career, Mozart wrote several pieces for her. After joining an opera troupe, Aloysia lost interest in him, and then Wolfgang’s cousin, Maria Anna Thekla, became his comforter. The nature of their relationship and the degree of intimacy are not entirely clear, but the “Letters to the Little Cousin” became scandalously famous in Mozart’s studies due to their obscenities, which do not go beyond toilet humor.

    Constanze, who became the composer’s wife, was Aloysia’s sister and also a singer. Mozart’s biographers are mostly indifferent to Constanze’s story because, unlike her sister, she did not achieve artistic success and did not influence her husband’s work in any way. Apparently, Mozart was happy in this marriage, despite various distressing circumstances, primarily the death of four children.

    Mozart Loved Obscene Humor and Was Not Particularly Smart

    Verdict: The first is true, the second is not.

    Mozart resorted to toilet humor even in letters, and these letters have reached us due to the carelessness of the addressees. Communicating with his cousin, Mozart did not shy away from expressions:

    And now I have the honor to ask how you are feeling, how is your health? Are your bowels in order? Is your skin smooth?—Tell me, have you not gotten tired of me yet? Do you often use chalk when writing? Do you remember me from time to time? Do you ever want to hang yourself? Were you ever mad at me? At poor fool? Would you like to make peace voluntarily, or else I could let out a loud one? Well, now you’re laughing to tears—victory!—Let our behinds become a symbol of peace! I knew you wouldn’t resist for long. Yes-yes, I always believe in my victory, and even if I have a bowel movement after lunch, I will still leave for Paris in two weeks. And if you want to reply to me, write from Augsburg right now, and write quickly so I can get the letter. If I’ve already left, then while waiting for a letter, I will receive only crap.

    Commentators on these letters have repeatedly noted that this kind of correspondence was commonplace for the residents of Salzburg in that era. Mozart’s parents also corresponded in a similar style.

    Mozart was far from stupid and was very well-educated. He spoke at least three European languages, wrote operas in Italian and German, knew Latin, and composed spiritual works in it. Throughout his life, he communicated with the most educated and intelligent people of his time. He demonstrated knowledge and intelligence in his art and in his reflections on music and its laws, which have come down to us thanks to his letters.

    Mozart Was Blind or Deaf

    Representation of Mozart’s left ear (left) and a normal ear (right)

    Verdict: False.

    He is often confused with George Frideric Handel, who lost his eyesight, and Ludwig van Beethoven, who went deaf.

    Mozart Wrote the “Requiem” Overnight at the Request of a Mysterious Stranger, Foreseeing His Own Death

    Verdict: This is partly true.

    There was indeed a mysterious stranger’s request for the “Requiem.” However, the identity of the commissioner was later revealed, and there was no mystique to his intentions. It was Franz von Walsegg zu Stuppach, an amateur composer, who commissioned the “Requiem” for his deceased wife, intending to pass it off as his own work. This explains the mysterious circumstances surrounding the commission—he did not want to reveal his name.

    Moreover, the “Requiem” was not written overnight (that feat belongs to the overture of “Don Giovanni”), and it was not even finished despite having ample time—the commissioner did not rush the composer, who was occupied with other urgent matters. After Mozart’s death, the work was completed by his pupil, Franz Xaver Süssmayr, according to Mozart’s notes. Süssmayr independently wrote the last three parts of the “Requiem.” As for the famous “Lacrimosa,” only the first eight bars were composed by Mozart—this is perhaps the most well-known musical theme he ever created.

    Mozart Was Poisoned by His Archrival, Salieri

    Verdict: This is unproven.

    Investigations into this case continue to multiply—sometimes scientific, but more often dubious. The rumors began immediately after Mozart’s death, not without the involvement of his widow, who claimed that the deceased composer himself had suspected something. This version was also discussed among the musicians of Vienna, with Salieri’s name even being mentioned, leading him to swear to his close friends that he had nothing to do with it.

    Salieri had no reason to be jealous: his position at court was much more secure than Mozart’s; he held a higher rank, and the success of his compositions had long been established. No signs of conflict or intrigue against Mozart were ever observed. On the contrary, Salieri had a reputation as a respectable man and an exceptional teacher—three geniuses, Beethoven, Schubert, and Liszt, all attended his school, and he never attempted to poison any of them. As for Mozart, he most likely died of a sudden kidney disease.

    The Poisoned Mozart Died in Poverty and Obscurity

    Verdict: False.

    This myth arose because Mozart was buried in a common grave, but this was unrelated to his financial status. According to an edict by Emperor Joseph II, burials in individual graves were a privilege reserved only for the noblest families. All others were buried five or six at a time, without coffins. Relatives were forbidden to accompany the deceased to the cemetery or to erect monuments and crosses on the graves. These were the emperor’s ideas of economy. The edict was later repealed, but by then, Mozart’s grave had already been lost. His music, however, remains.

  • Hits Sound More Monotonous Today Than in 1950

    Hits Sound More Monotonous Today Than in 1950

    Today’s popular songs are significantly simpler in structure compared to those from 70 years ago. This could be due to the development of new genres like disco or hip-hop, as well as technical innovations that have influenced the melodies of popular songs.

    From Elvis, the Rolling Stones, and the Beatles, through Pink Floyd, Roxette, and Michael Jackson, to Beyoncé and Taylor Swift, some music is more popular and successful than other works. However, browsing the charts of previous decades, one tends to encounter more musically exceptional songs than in today’s uniform chart successes. Popular songs and earworms also seem to have become noticeably faster over time.

    Can we objectively prove this, or is it merely a subjective impression? Moreover, what has driven this development?

    Comparing chart Successes

    To investigate this, Madeline Hamilton and Marcus Pearce from Queen Mary University of London studied the evolution of popular earworms over the past decades. They analyzed the main melodies of over 1,100 singles that reached the top 5 of the US Billboard charts at the end of each year between 1950 and 2022. They mathematically compared these melodies based on various musical characteristics, such as rhythm and tonal structure, diversity, number, and duration of notes.

    Faster, but More Boring?

    The analysis revealed that the complexity of rhythms and pitch arrangements decreased during this period.

    Simultaneously, the average number of notes played per second increased, as did the number of repetitions, making the melodies faster and more monotonous over time.

    Within this trend, two years stood out: 1975 and 2000, where melodic complexity sharply decreased. 1996 also saw a significant change in music history, although it was less drastic than in the other two years.

    New Genres Changed Hit Melodies

    Hamilton and Pearce suspect that the changes in 1975 could represent the rise of new preferences and music genres such as New Wave, Disco, and Stadium Rock. The “revolutions” in 1996 and 2000 could represent the rise of hip-hop and the introduction of digital audio workstations that allowed the repeated playback of audio loops.

    Compared to previous studies, the researchers conclude that these musical “revolutions” took place several years later than previously assumed.

    More Monotonous Doesn’t Necessarily Mean Worse

    The researchers conclude that these innovations have led to simpler popular melodies. However, they emphasize that this does not necessarily mean music has become less complex overall or “worse.” The quality and combination of sounds could have developed independently of the melodies, or even in the opposite direction.

    For example, simpler melodies could also be a consequence of modern songs becoming faster; artists may have avoided complex melodies to not overwhelm listeners. Artists may have focused more on sound quality or other features than melody, which only became possible with digital techniques.

    The study also does not reflect the entire history of music. “Since the sample only contains the five most popular songs of each year, it cannot be said to represent US American or Western pop music in general. Therefore, we emphasize that a much larger dataset of melodies is needed to verify the conclusions of the study,” the researchers write.

  • Was Beethoven’s Musicality in His Genes?

    Was Beethoven’s Musicality in His Genes?

    The renowned composer Ludwig van Beethoven is hailed as a musical prodigy, but what does his genetic makeup reveal about him? A research team has now scrutinized this more closely. The surprising finding is that, at least as a common marker for musicality, Beethoven’s genome appears to be not particularly outstanding. According to the team, the composer ranks only in the upper midfield in terms of this polygenic index. However, this genetic marker only captures a small aspect of musicality.

    Many eminent composers, including Mozart, Beethoven, and Bach, are considered prodigies with exceptional musical abilities. But what distinguishes them? Are certain genes responsible for the remarkable musical abilities of such individuals?


    Twin studies suggest that musicality is genetically determined to be about 42 percent. A recent genome-wide association study also identified 69 gene variants that contribute to a strong sense of rhythm and bolster other aspects of musicality.

    A Comparative Look at Beethoven’s Genome

    At this point, Beethoven and his genetic material come into play. Researchers have already gained initial insights into Beethoven’s genome, particularly the genetic basis of his illnesses, thanks to the preservation of DNA in some locks of the composer’s hair. “We have now extended this approach to musicality,” said Laura Wesseldijk and her colleagues. For this purpose, they searched the composer’s genome for the 69 gene variants associated with musicality and sense of rhythm.

    “We calculated this polygenic index for Beethoven and then compared it with two population-based datasets of thousands of modern individuals,” explains Wesseldijk and her team. The comparison groups consisted of approximately 5,600 individuals from a Swedish twin registry and 6,150 individuals from a US genome database, each of whom had been tested for rhythm and musicality.

    “We deliberately did not make any predictions about where Beethoven’s polygenic index would lie because, with our study, we wanted to primarily highlight the limitations of this approach,” emphasize the researchers.

    Genetically Good, But Not Outstanding

    The genome comparisons revealed something surprising: Beethoven ranks in the ninth and eleventh percentiles of both populations with his polygenic musicality index. Thus, the composer has more music-specific gene variants than around 90 percent of the comparison individuals, but this position is not outstanding.

    After all, almost ten percent of the comparison individuals have a higher index than he does, as determined by Wesseldijk and her team.

    “At first glance, these results seem quite confusing,” writes the research team. “Because Beethoven, one of the most famous musicians in history, scores relatively unremarkably here.” But why? ” Obviously, it would be wrong to conclude solely from the results of the polygenic index that Beethoven’s musical abilities were not particularly remarkable,” explains the team. Because the musician’s compositions prove the opposite.


    Why Genes Lie

    But what is the reason for Beethoven’s moderate genetic outcome? As Wesseldijk and her colleagues explain, there are several reasons for this: Firstly, polygenic indices like the one examined here only capture a small fraction of genetic effects because they only capture common gene variants, not rare ones. “Secondly, PGIs are approximations at the population level, which can only make limited, accurate predictions for an individual,” the team says.

    And finally, the most important point: “Musicality is not a single trait but a multi-component suite of abilities,” explains the researchers. These abilities, in turn, are based on a mixture of various genetic factors, some of which only influence specific aspects of musicality. Therefore, Beethoven’s exceptional musicality most likely stems from genetic factors.

    “A Valuable Lesson”

    Accordingly, these results do not question that genetic makeup influences a person’s musical talent. However, they also illustrate the limits of genetic tests. “We believe that the significant disparity between this DNA-based prediction and Beethoven’s musical genius is a valuable lesson,” says co-author Simon Fisher of the Max Planck Institute for Psycholinguistics.

    “It shows that one should be skeptical when, for example, someone claims that a genetic test can reliably determine whether a child will be musically talented or talented in another field,” the researcher continues.

  • How and with Which Instruments Is the Pitch of a Non-Musical Sound Measured?

    How and with Which Instruments Is the Pitch of a Non-Musical Sound Measured?

    Sound refers to the aural impression produced by an acoustic wave. Understanding the nuances of music is essential for telling it apart from “non-musical” noise. The term “music” refers to any sequence of sounds that has been arranged in a certain way. It may be described in terms of pitch, duration, and timbre. If you can’t identify the pitch, what you’re hearing isn’t sound; it’s just noise.

    It’s possible to make a noise by hitting any item, but it’s usually not the same as a musical instrument’s sound since the pitch of the noise can’t be pinpointed to a certain note on the musical scale.

    Noise is a very intricate frequency combination in which no one frequency can be isolated as the dominant force. This is true of percussion instruments such as drums, bass drums, and cymbals.

    Xylophones, timpani, and bells are all examples of instruments in which a single frequency predominates while nevertheless producing a distinct pitch. The percussion instruments all have this characteristic manner of emission.

    The term “percussion instruments” refers to a broad class of musical instruments that produce audible vibrations when hit, shaken, or rubbed. The sound is produced by the entire item vibrating and releasing air molecules. Musicologists have given them the label “idiophones” because of their unique abilities.

    There are musical instruments here whose sounds cannot be placed on a musical scale. They might emphasize the music’s rhythm by highlighting its prominent beats, or they can provide a distinct hue to certain sections of the score.

    In contrast, some may be identified by their pitch note and have a melodic function.

    Common noise-measuring tools include the sound level meter, audio meter, and integrated sound level meter.

    Common noise measuring tools include the sound level meter audio meter and integrated sound level meter

    In terms of its “pitch,” a sound wave is what we hear. Scientists use the term “compression wave” to describe the phenomenon of air vibration. This wave travels through the air at a pace of around 1080 feet (330 meters) per second, therefore conveying audible vibrations.

    The frequency of an object is defined as the rate of vibration in cycles per second. Frequency is measured in hertz, often abbreviated Hz. The frequency of a sound wave is what gives it its pitch. On a tuning fork, the A note has a frequency of 440 hertz. This translates to a frequency of 440 oscillations per second for the blades.

    In the same way that decibels can be measured using a sound level meter, “pitch” may also be quantified in this way. There is a sweet spot for human hearing somewhere between 500 Hz and 6 kHz, and your sensitivity drops off significantly outside of that range. Sound level meters and dosimeters rely on frequency weightings to accurately record and report the decibels we’re exposed to. There are built-in electronic filters that can be employed to modify the sensitivity of the instrument’s noise measurements.

    The frequency and intensity of a sound are two different things. Low-pitched sounds have a low frequency, whereas high-pitched ones have a high frequency. Thus, hertz (Hz) is the unit of frequency measurement.

    The louder the sound, the greater the amplitude of the vibration; conversely, the weaker the sound, the smaller the amplitude. It is commonly expressed in decibels (dB).

  • Why does our musical scale have eight tones?

    Why does our musical scale have eight tones?

    Melodies are created by stringing together a variety of tones in order to create music. Intervals are the lengths between tones in a piece of music. If you want a piece of music to sound especially harmonic to human hearing, the intervals between the tones are quite influential. Tones are most often symbolized in our society by the notes that make up the musical scale. An octave is comprised of eight tones, and if you add all of the semitones, there are even twelve total tones. But where exactly did this breakdown into eight or twelve steps happen in the first place? Why are some intervals on the piano scale sound more harmonic?

    Tones, when seen from a purely physical perspective, are nothing more than sound waves that have a certain frequency. In this way, each tone can be assigned a frequency. C0, located at the lower end of the audible range and with a frequency of 16.35 hertz, is the tone that is considered to be the lowest tone used in music. The frequency of 440 hertz is what causes a tuner to generate an A4 note, which is considered a concert pitch. The tone A5 is eight tones, or one octave, higher than the previous tone. Surprisingly, this tone has a frequency that is precisely twice as high as the previous one: 880 hertz. This relationship is the same for all tones; an octave change always means that the frequency has doubled.

    The frequency of a tone is not always primarily emitted by a musical instrument, and neither is it always emitted by the human voice. If this were the case, then the sound produced by each instrument would be exactly the same. The “pure” sound of a frequency may be heard in beeps created by a computer; these sounds have a frequency known as a sine frequency. When singing or playing music, there are almost always other tones that are resonating, and these other tones are what comprise the unique sound of an instrument. “Overtones” are the term used to describe these extra tones. The basic tone of a person’s voice comes from the vocal cords. Overtones, on the other hand, come from the rest of the vocal tract, including the trachea.

    Overtones determine perfect intervals

    There are frequency ranges in every instrument, especially the voice, that contain frequency ranges in which there are a particularly large number of particularly strong overtones. These frequency ranges are referred to as formants. These formants are especially significant when it comes to the voice since they are the ones that govern how we interpret vowels.

    Furthermore, whether singing or speaking, the formants almost always correlate to a perfect interval. This is something that we are familiar with, thanks to the musical scale. It is reasonable to assume that our earliest ancestors had an innate preference for these tones and intervals. Different tonal systems from other civilizations show that the scale used here is not the only way to play notes.

    Intervals such as the octave and the fifth may be found in the music of practically every civilization on the planet. This suggests that the perception of these intervals is universal, or at the very least, shared by all individuals. It is very possible that the division of the musical scale as we know it originated from this intuitive awareness of “perfect” intervals. Certain tones and intervals just seem “correct” to our ears.

  • History of Sound Recording: The Inventors and the Devices

    History of Sound Recording: The Inventors and the Devices

    What is the story of the invention of sound recording and the first sound devices? Until just over a century ago, the only music people listened to was live performances. The development of technology for recording and replaying sound has not only changed the way we listen to music but has also made broadcasting, filming, and audio archiving applications possible.

    The Invention of Audio Recording

    Frenchman Edouard-Leon Scott’s phonautograph of 1857 was the first instrument capable of recording sound. It recorded sound with a moving needle on a carbon-coated surface. In 1877, the American Thomas Edison invented the phonograph. This was the first instrument that could record and play back sound. Primitive sound recorders worked mechanically. Sound vibrations collected by a tube moved a needle to make scratches on a disc or cylinder.

    In the 1920s, the invention of the microphone ushered in the electrical age of sound recording. Soon after, sound was reproduced in high quality and volume through powerful loudspeakers driven by electromagnets.

    After 1945, music was recorded on vinyl records that rotated at 33 or 45 revolutions per minute (rpm) (earlier records were played at 78 rpm). Magnetic instruments were also developed that recorded sound by creating different magnetic patterns, rather than physical pits on a disc.

    The next milestone was digital sound recording. This type of recording was made for more powerful and functional systems. Later, the first compact discs and digital audio formats such as MP3 were introduced for storing large amounts of music on small devices and for unlimited music downloads via the internet.

    From the Music Box to Digital Audio

    1815 – Multi-Cylinder Music Box

    First produced in Switzerland in 1815, this music box contains a rotating cylinder with spikes on it, which enter the teeth on a steel honeycomb. In 1862, a system with interchangeable cylinders was invented to play different models.

    1857 – Phonautograph

    Edouard-Leon Scott invented the first instrument capable of recording sound, but it could not play it back.

    1876 – Automatic Piano

    The automatic piano became famous when it was shown at an exhibition. This instrument contained an electromagnet and a paper music roll.

    1877 – Edison’s Phonograph

    Thomas Edison’s phonograph was the first instrument that could both record and playback sound. Sound vibrations are picked up by a tube and recorded on a cylinder covered with tin foil.

    1888 – Gramophone

    The gramophone, invented by Emile Berliner, uses shellac discs. These discs can be copied many times over in a brass container.

    1898 – Magnetic Voice Recorder

    Danish engineer Valdemar Poulsen invented the telegraph. It was the first instrument to record and playback sound magnetically. With a cable wound around a cylinder, it records the changes in the magnetic field caused by sound vibrations.

    1925 – First Microphone

    Microphones that pick up vibrations have replaced the tubes. In these microphones, vibrations are transmitted to electromagnets and changes in the electrical signals move the needle.

    1978 – Cassette Player

    German-Brazilian Andreas Pavel’s 1972 Stereobelt is a small, portable, battery-powered player with headphones and a cassette player. In 1978, Sony introduces the Sony Walkman, a portable music player.

    1982 – Compact Disc (CD)

    CDs store large amounts of audio data and can be read back with a laser. They soon replaced vinyl records, which could be easily scratched.
