Child prodigy Mozart made his first public appearance, at six years of age, in a harpsichord and piano concert tour of Munich and Vienna. One year later (1763) his first published composition was distributed in Paris. In the following year young Mozart visited London where he studied with J. S. Bach's youngest son, Johann Christian. After several tours across Europe, Mozart became first Konzertmeister (1769), then organist (1779), to the Archbishop of Salzburg. In 1781 Mozart settled in Vienna where, seven years later, he became composer to the Emperor. Too numerous to list here, Mozart's works represent the best of Viennese classicism.
