Wolfgang Amadeus Mozart was an Austrian composer, widely recognised as one of the greatest composers in the history of Western music. With Haydn and Beethoven, he brought to its height the achievement of the Viennese Classical school. Unlike any other composer in musical history, he wrote in all the musical genres of his day and excelled in every one. His taste, his command of form and his range of expression have made him seem the most universal of all composers; yet, it may also be said that his music was written to accommodate the specific tastes of particular audiences.
Since he was a young boy, Mozart's early talent for music was remarkable. At three, he was picking out chords on the harpsichord; at four, playing short pieces; at five, composing. There are anecdotes about his precise memory of pitch, about his scribbling a concerto at the age of five and about his gentleness and sensitivity (he was afraid of the trumpet). Just before he was six, his father took him and Nannerl, also highly talented, to Munich to play at the Bavarian court, and a few months later, they went to Vienna and were heard at the imperial court and in noble houses.
