Wolfgang Amadeus Mozart (27 January 1756 – 5 December 1791) was a Classical composer and musician. He completed more than 800 works in his life—including outstanding examples of most of the genres of his time: symphonies, concertos, chamber music, opera, and choral music—and is regarded as one of the greatest composers in the history of Western music.
Born in Salzburg, Mozart quickly emerged as a child prodigy under the training of his father Leopold, a skilled pedagogue. At the age of five he was already competent on keyboard and violin, had begun to compose, and had performed before European royalty. His father took him on a grand tour of Europe and then three trips to Italy. At 17 he was a musician at the Salzburg court but grew restless and travelled in search of a better position. A fruitless journey in search of employment (1777–1779) led him to Paris, Mannheim, Munich, and eventually back to Salzburg. During this time he wrote his five violin concertos, the Sinfonia Concertante, various masses, and the opera Idomeneo.
While he was visiting Vienna in 1781, Mozart's quarrels with his Salzburg employers came to a head and he was dismissed. He chose to remain in Vienna, where he stayed for the rest of his life, achieving fame and some financial success, but no long-term security. During Mozart's early years in Vienna he produced several notable works, such as the opera Die Entführung aus dem Serail, the Great Mass in C minor, the "Haydn" Quartets and a number of symphonies. Throughout his Vienna years Mozart composed more than a dozen piano concertos, many considered some of his greatest achievements.
In the final years of his life, he wrote many of his best-known works, including his last three symphonies, culminating in the Jupiter, the serenade Eine kleine Nachtmusik, his Clarinet Concerto, the operas Le nozze di Figaro, Don Giovanni, Così fan tutte and Die Zauberflöte, the Piano Concerto No. 27 and his Requiem. The Requiem was largely unfinished at the time of his death at the age of 35.
Modern scholars rely on various source materials in writing Mozart's biography. First, there are about 1500 pages of family letters, often vivid and entertaining, mostly written when travel separated Mozart from his kin. There are also early biographies, written with input from Mozart's sister Nannerl, his wife Constanze, and others who knew him well. Old documents, such as newspaper stories and government records, have been located in libraries and archives, annotated, and published. Lastly, the composer's surviving manuscripts shed light on the history and dating of his compositions: there are sketches, drafts, dated autographs of completed works, and Mozart's personal catalog.
Mozart biographers all work from these same sources, but they often disagree on crucial points. The disagreements arise in part from the need to judge how much to believe a source who had strong motivation to diverge from the truth. A source once widely used but now judged untruthful is the publisher Friedrich Rochlitz, who sought to increase posthumous sales of Mozart's works by publishing false, vivid stories about him. A trend across time, noted in Stafford (2003), is for biographers to be less credulous (e.g., in believing Rochlitz), less sentimental, and more sensitive to information about Mozart's own society and times.
Wolfgang Amadeus Mozart was born on 27 January 1756 to Leopold Mozart and Anna Maria, née Pertl, at Getreidegasse 9 in Salzburg. Salzburg was the capital of the Archbishopric of Salzburg, an ecclesiastical principality within the Holy Roman Empire, located in what is now Austria. He was the youngest of seven children, five of whom died in infancy. His elder sister was Maria Anna Mozart, nicknamed "Nannerl". Mozart was baptised the day after his birth, at St. Rupert's Cathedral in Salzburg. The baptismal record gives his name in Latinised form, as Joannes Chrysostomus Wolfgangus Theophilus Mozart. He generally called himself "Wolfgang Amadè Mozart" as an adult, but his name had many variants.
Leopold Mozart, a native of Augsburg, then an Imperial Free City in the Holy Roman Empire, was a minor composer and an experienced teacher. In 1743, he was appointed as the fourth violinist in the musical establishment of Count Leopold Anton von Firmian, the ruling Prince-Archbishop of Salzburg. Four years later, he married Anna Maria in Salzburg. Leopold became the orchestra's deputy Kapellmeister in 1763. During the year of his son's birth, Leopold published a successful violin textbook, Versuch einer gründlichen Violinschule.
When Nannerl was seven, she began keyboard lessons with her father, while her three-year-old brother looked on. Years later, after her brother's death, she reminisced:
He often spent much time at the clavier, picking out thirds, which he was ever striking, and his pleasure showed that it sounded good. ... In the fourth year of his age his father, for a game as it were, began to teach him a few minuets and pieces at the clavier. ... He could play it faultlessly and with the greatest delicacy, and keeping exactly in time. ... At the age of five, he was already composing little pieces, which he played to his father who wrote them down.
These early pieces, K. 1–5, were recorded in the Nannerl Notenbuch.
Leopold was their only teacher. Along with music, he taught his children languages and academic subjects. While Leopold was a devoted teacher to his children, there is evidence that Mozart was keen to progress beyond what he was taught: his first ink-spattered composition and his precocious efforts with the violin were of his own initiative and came as a surprise to Leopold, who eventually gave up composing when his son's musical talents became evident. Leopold dubbed Wolfgang "the miracle whom God allowed to be born in Salzburg."
While Wolfgang was young, his family made several European journeys in which he and Nannerl performed as child prodigies. These began with an exhibition in 1762 at the court of Prince-elector Maximilian III of Bavaria in Munich, and at the Imperial Courts in Vienna and Prague. A long concert tour followed, spanning three and a half years, taking the family to the courts of Munich, Mannheim, Paris, London, The Hague, Amsterdam, Utrecht, and again to Paris, and back home via Zürich, Donaueschingen, and Munich. During this trip, Wolfgang met many musicians and acquainted himself with the works of other composers. A particularly significant influence was Johann Christian Bach, whom he visited in London in 1764 and 1765. When he was eight years old, Mozart wrote his first symphony, most of which was probably transcribed by Leopold.
The family trips were often challenging, and travel conditions were primitive. They had to wait for invitations and reimbursement from the nobility, and they endured long, near-fatal illnesses far from home: first Leopold (London, summer 1764), then both children (The Hague, autumn 1765). The family again went to Vienna in late 1767, where both Wolfgang and Nannerl caught smallpox during an outbreak, though they quickly recovered. They remained there until December 1768.
After one year in Salzburg, Leopold and Wolfgang set off for Italy, leaving Anna Maria and Nannerl at home. This tour lasted from December 1769 to March 1771. As with earlier journeys, Leopold wanted to display his son's abilities as a performer and a rapidly maturing composer. Wolfgang met Josef Mysliveček and Giovanni Battista Martini in Bologna and was accepted as a member of the famous Accademia Filarmonica. According to a letter Leopold wrote home to Salzburg, while in Rome Wolfgang heard Gregorio Allegri's Miserere twice in performance in the Sistine Chapel. He subsequently wrote it out from memory, thus producing the "first unauthorised copy of this closely guarded property of the Vatican". The details of this account are, however, disputed.
In Milan, Mozart wrote the opera Mitridate, re di Ponto (1770), which was performed with success. This led to further opera commissions. He returned with his father twice to Milan (August–December 1771; October 1772 – March 1773) for the composition and premieres of Ascanio in Alba (1771) and Lucio Silla (1772). Leopold hoped these visits would result in a professional appointment for his son, and indeed ruling Archduke Ferdinand contemplated hiring Mozart, but owing to his mother Empress Maria Theresa's reluctance to employ "useless people", the matter was dropped and Leopold's hopes were never realised.
