He possessed the superhuman cognitive ability to compose entire symphonies entirely in his head. Before his quill ever touched a piece of parchment, he would mentally construct, arrange, and perfectly orchestrate highly complex pieces of music, treating the actual physical writing process merely as a tedious act of dictation.
His astonishing musical memory was practically photographic. As a young teenager, he visited the Vatican and listened to a highly guarded, secret performance of Gregorio Allegri’s Miserere, and upon returning to his lodging, he sat down and perfectly transcribed the entire nine-part choral piece completely from memory after hearing it just once.
He owned a bizarre pet starling that could actually sing his concertos. While walking past a Vienna pet shop, he heard a starling whistling the exact melody from his recently composed Piano Concerto No. 17 in G Major, prompting him to instantly buy the bird and keep it as a beloved, musically collaborative companion for three years.
An intense gambling and billiards addiction completely ruined his finances. Despite earning massive sums of money from his highly successful operas and royal commissions, he was deeply addicted to high-stakes card games and private billiards matches, leading to a desperate cycle of borrowing massive amounts of money from his friends and fellow freemasons.
He suffered from a unique physical deformity that is now named after him. He was born with a rare congenital ear defect where the upper cartilage is folded over and lacks a typical lobe, an anatomical quirk that is now officially recognized in modern medicine as the Mozart ear.
His sense of humor was notoriously childish and deeply scatological. Surviving historical letters written to his family members, particularly his cousin Maria Anna Thekla, reveal an absolutely shocking obsession with crude toilet humor, filled with bizarre rhyming jokes and highly enthusiastic references to bodily functions.
The name Amadeus was almost never actually used during his lifetime. Though it is the name history remembers him by, he was baptized as Joannes Chrysostomus Wolfgangus Theophilus, and as an adult, he preferred to sign his letters using the French translation Amadè or the Italian Amadeo, rarely ever writing the Latin version.
He harbored a secret, intense dislike for the sound of the flute. Despite composing some of the most beautiful and iconic flute concertos in the classical repertoire, he actively complained in his private letters about the instrument, claiming he only wrote for it when he was desperately strapped for cash and commissioned by wealthy patrons.

The famous myth that Antonio Salieri murdered him is completely false. While the movie Amadeus popularized the idea of a lethal, jealous rivalry, historical records prove the two composers were actually mutually respectful professional colleagues in Vienna, and they even co-wrote a cantata together that was recently rediscovered in a Czech museum.
His childhood tours were incredibly grueling and nearly fatal. To showcase his prodigy status, his father dragged him across Europe on brutal carriage journeys for years at a time, exposing the young boy to severe exhaustion and deadly aristocratic diseases, including a terrifying bout of smallpox that nearly blinded and killed him.
The mysterious commissioning of his final Requiem sounds like a ghost story. A mysterious, anonymous messenger truly did show up at his door to commission the death mass, but it was not a phantom or a rival; it was simply a servant of Count von Walsegg, an eccentric aristocrat who secretly wanted to pass the brilliant composition off as his own work.
He was deeply entrenched in the secret society of Freemasonry. Joining the secretive fraternity in Vienna had a massive impact on his personal philosophy and professional networking, heavily influencing the intricate musical symbolism and the overarching enlightenment themes found in his famous opera, The Magic Flute.

The myth of his burial in a pauper’s grave is a historical misunderstanding. While it is true he was not buried in an opulent, marked tomb, he was laid to rest in a common grave at the St. Marx Cemetery, which was absolutely standard protocol for middle-class citizens in Vienna under the strict burial laws of Emperor Joseph II.
He kept a veritable zoo of expensive pets in his small apartments. In addition to his famous musical starling, he recklessly spent his dwindling funds on a variety of animals, including a canary, a pet dog, and even a horse, which only exacerbated his crippling financial debts and frustrated his wife, Constanze.
His handwriting reveals his incredibly frantic mental pace. Historians analyzing his original musical manuscripts have noted that his musical notation flows rapidly and flawlessly without crossed-out mistakes, but the accompanying text and lyrics are often sloppy and rushed, proving his mind was moving far faster than his hand could possibly write.
