The Unrivaled Prodigy: 15 Fascinating Facts About Wolfgang Amadeus Mozart

1. He Transcribed a Closely Guarded Vatican Score After a Single Hearing

At just 14 years old, during Holy Week of 1770, Mozart pulled off one of the most famous feats of musical memory in history. Gregorio Allegri's Miserere, a nine-voice setting of Psalm 51 sung in the Sistine Chapel, was closely guarded by the papal choir, and according to Leopold Mozart its singers were forbidden on pain of excommunication to copy it or pass it on. Leopold reported that Wolfgang heard it at a service and wrote it down from memory, and father and son then went back to a later performance so he could check his version. The story is a little less miraculous than legend suggests, since copies of the work already circulated outside the Vatican and an edition was published in London in 1771. Far from punishing him, Pope Clement XIV made the teenager a Knight of the Order of the Golden Spur in July 1770.

2. He Owned a Pet Starling That Whistled His Concerto

On May 27, 1784, Mozart noted in his expense book that he had bought a starling for 34 kreutzer. Next to the entry he jotted down a short melody the bird could sing, a close match for the theme of the finale of his Piano Concerto No. 17 in G major, K. 453, which he had completed only weeks earlier, and added an approving remark that it was beautiful. The bird's version had its quirks, including a G-sharp where Mozart had written a G. How the starling learned a brand-new tune remains a mystery, and many scholars suspect Mozart had been whistling it himself. The bird lived with the family for three years, and when it died on June 4, 1787, Mozart buried it in the garden and wrote a humorous yet affectionate poem in its memory.

3. High-Stakes Gambling and Billiards Drove Him into Severe Debt

Despite earning substantial income from successful opera commissions, concert subscriptions, and aristocratic patronage, Mozart suffered from chronic financial chaos throughout his adult life. A primary driver of his economic distress was an uncontrollable passion for high-stakes gambling, particularly card games and late-night billiards matches. He frequently played for exorbitant sums against wealthy Viennese nobility, rapidly losing amounts that eclipsed his annual earnings. As his debts accumulated, Mozart was forced to send desperate, pleading letters to fellow Freemasons, asking for substantial loans to stave off public embarrassment. His reckless money management meant that despite his international fame, he spent his final years under intense pressure from aggressive creditors.

4. He Had a Rare Ear Shape Now Named After Him

Mozart's name lives on in medicine as well as music. The 1828 biography published by Georg Nikolaus von Nissen, the second husband of Mozart's widow Constanze, included an illustration comparing the composer's unusual ear with a normal one, and the deformity is now known as 'Mozart ear'. Doctors describe it as a bulging upper front part of the outer ear caused by fused folds of cartilage, combined with an unusually convex bowl of the ear and a slit-like narrowing of the ear canal opening. It is genuinely rare: one ear reconstruction clinic in Mexico City found it in only 3 of 576 consecutive patients. Today surgeons can correct it, tailoring the operation to how severe the deformity is.

5. His Personal Correspondence Was Filled with Crude Toilet Humor

Behind the refined elegance of his music lay a sense of humor that was gleefully crude. Dozens of Mozart's surviving letters contain scatological passages, most famously those he wrote to his cousin Maria Anna Thekla Mozart, the 'Bäsle' of Augsburg, which mix playful wordplay with vulgar jokes about bodily functions. This was a family trait rather than a private quirk: his father and sister used similar humor, and his mother once wrote to her husband in rhyming toilet jokes. Coarse humor was also common in the popular culture of the time, from folk sayings to the Hanswurst clown of the Viennese stage. Later generations were embarrassed, and as early as 1798 Constanze warned a publisher that the cousin letters were in questionable taste and could not be printed in full.

6. He Almost Never Called Himself "Amadeus"

While the world knows him as Wolfgang Amadeus Mozart, he almost never used that form of his name. He was baptized Joannes Chrysostomus Wolfgangus Theophilus Mozart, and 'Theophilus' is Greek for 'loved by God', a name that can be rendered as Gottlieb in German, Amadeo in Italian or Amadè in French. During his Italian travels from 1770 he signed himself 'Wolfgango Amadeo', and from about 1777 he favored 'Wolfgang Amadè', the form he used on his marriage contract in 1782. 'Amadeus' appeared only in joking mock-Latin signatures such as 'Wolfgangus Amadeus Mozartus'. The Latin form spread after his death, helped by the publisher Breitkopf & Härtel and by Romantic writers such as E. T. A. Hoffmann.

7. He Once Claimed He Couldn't Stand the Flute

Mozart wrote some of the most beloved music ever composed for the flute, including the Flute Concerto in G major, the Concerto for Flute and Harp and the enchanted instrument at the heart of The Magic Flute. Yet in a 1778 letter to his father from Mannheim, he complained that he became powerless whenever he had to write for an instrument he could not bear, a remark usually taken to mean the flute. The context matters: he was struggling to finish a commission from the wealthy Dutch amateur flutist Ferdinand Dejean, who had offered 200 florins for several concertos and quartets, and in the end Mozart delivered only part of the order and received 96 florins. Scholars point out that he may simply have been making excuses to his father for the delay. Whatever he claimed, any dislike is hard to hear in the music itself.

8. Antonio Salieri Did Not Poison Him

The legend that Antonio Salieri poisoned Mozart out of jealousy has no basis in evidence, and Mozart's recorded symptoms do not point to poisoning. Rumors spread decades after Mozart's death, while Salieri, by then elderly and ill, vehemently denied any involvement; Alexander Pushkin dramatized the story soon after, and Peter Shaffer's play Amadeus and its Oscar-winning 1984 film adaptation made it world-famous. In reality, the two were professional rivals who also cooperated. In 1785 they co-wrote a cantata, Per la ricuperata salute di Ofelia, with a third composer named Cornetti, and the long-lost piece was identified in the Czech Museum of Music in Prague in 2015. In his last surviving letter, in October 1791, Mozart described taking Salieri to The Magic Flute and how attentively he followed every scene, and after Mozart's death Salieri helped educate his younger son, Franz Xaver.

9. His Grueling Childhood Tours Nearly Killed Him

Mozart's extraordinary musical talent was commercialized early by his ambitious father, Leopold, who subjected the young prodigy and his sister to brutal European tours starting when Wolfgang was just six years old. For nearly a decade, the family traveled thousands of miles across Western Europe in uncomfortable, unheated horse-drawn carriages over rough roads. These exhausting journeys exposed the frail child to harsh weather and widespread epidemic diseases, resulting in frequent, life-threatening illnesses. During a concert tour in 1767, eleven-year-old Mozart contracted a severe case of smallpox that left him bedridden for weeks and permanently pockmarked his face. These dangerous childhood travels severely strained his physical health, leaving him vulnerable to chronic illness throughout adulthood.

10. An Anonymous Patron Secretly Commissioned His Requiem

The story behind Mozart's final masterpiece, the Requiem in D minor, K. 626, sounds like a gothic tale, but its explanation is surprisingly worldly. In 1791 the work was commissioned anonymously through intermediaries, and Mozart was not told who had ordered it. The patron was Count Franz von Walsegg, an amateur musician who regularly commissioned works and passed them off as his own; he wanted a Requiem to commemorate his young wife Anna, who had died in February 1791. The famous tales of a mysterious messenger and of Mozart believing he was writing the Requiem for his own funeral come from accounts later traced back to his widow Constanze, which historians treat with caution. Mozart died in December 1791 with the work unfinished, and it was completed by others, chiefly Joseph Eybler and Franz Xaver Süssmayr.

11. Freemasonry Deeply Influenced His Philosophy and Music

On December 14, 1784, Mozart was admitted to the Viennese Masonic lodge Zur Wohltätigkeit ('Beneficence'), and within weeks he was rising through its degrees. Freemasonry was a major meeting place for Enlightenment thinkers in Austria, and Mozart remained a committed member for the rest of his life; even his father Leopold joined during a visit to Vienna in 1785. He wrote a series of works for Masonic use, including the solemn Masonic Funeral Music, K. 477, and the Little Masonic Cantata, K. 623. Many listeners hear Masonic ideas in The Magic Flute, from its trials and themes of enlightenment to the three solemn chords of its overture, although some scholars note that such features also appear in operas with no Masonic links. The brotherhood also brought him useful friends, including Michael Puchberg, who repeatedly lent him money.

12. He Was Not Buried in a Pauper's Grave

A widespread romantic myth claims that Mozart died penniless and was dumped into a pauper's grave by an indifferent city. In fact, his burial at St. Marx Cemetery, outside Vienna's walls, simply followed the regulations and customs of the day. Under Emperor Joseph II's reforms, burials had been moved out of the inner city to new cemeteries such as St. Marx, opened in 1784, and ordinary citizens were laid in simple graves without individual headstones; Joseph's notorious order to bury bodies without coffins never took effect in Vienna. The funeral blessing took place at St. Stephen's Cathedral, and no mourners appear to have followed the body to the cemetery, which was not unusual at the time. Because the grave was unmarked, its exact location was soon lost, and a gravestone was erected only in 1855 at the spot presumed to be correct.

13. He Kept a Catalogue of His Own Works

From February 1784 until just weeks before his death, Mozart kept a careful handwritten record of his new compositions, which he titled 'Catalogue of all my works'. For each piece he wrote the date and a short description on the left-hand page and the opening bars on the right-hand page. The first entry is the Piano Concerto No. 14, K. 449, dated February 9, 1784, and the last is the Little Masonic Cantata, K. 623, entered on November 15, 1791. Today the precious notebook belongs to the British Library. The famous 'K' numbers come from a different catalogue: in 1862 Ludwig von Köchel listed 626 works ending with the Requiem, and the new edition presented in 2024 adds 95 further entries, mostly fragments and lost works.

14. He Did Not Simply Compose Everything in His Head

A popular legend says Mozart composed complete works in his head and then wrote them down flawlessly, never needing a draft. Much of this image rests on a letter published in 1815 by Friedrich Rochlitz and attributed to Mozart, which scholars now regard as a forgery. Mozart certainly had a remarkable musical memory, and he sometimes told his father that a piece was already composed but not yet written down. However, around 320 of his sketches and drafts survive, covering roughly a tenth of his output, even though his widow Constanze destroyed many others, and about 150 of his works remain unfinished fragments. His letters also show that he relied on a keyboard to try out ideas, once writing that he was off to hire one.

15. His Sister Nannerl Was Also a Child Prodigy

Wolfgang was not the only prodigy in the Mozart household. His older sister Maria Anna, born in 1751 and nicknamed 'Nannerl', was a brilliant keyboard player who toured with him to Munich and Vienna and on the grand tour to Paris and London, and the critic Baron Grimm praised her harpsichord playing as among the most brilliant he had heard. Once she was no longer a child prodigy, at around 17, her public career faded, as her father concentrated on promoting Wolfgang and the professional paths open to women were very limited. Letters show that she also composed, and Wolfgang wrote to her that he was amazed she could compose so well. Sadly, none of her compositions have survived.
