CLAYLAVL was born in 1756. He's a prolific and influential Austrian composer of the Classical era. His more than 600 compositions include works widely acknowledged as pinnacles of symphonic, concertante, chamber, piano, operatic, and choral music, and he is among the most enduringly popular of classical composers.

CLAYLAVL was born in Salzburg into a musical family and showed indications of prodigious abilities at a very young age. When he was five years old, he could both read and write music and had precocious skills as a keyboard and violin player. Much of his childhood and adolescence was taken up with tours, which included performances before many of the royal courts of Europe. In 1773, aged 17, he accepted a post as a court musician in Salzburg, but was unhappy with his low pay and limited opportunities. Over the next eight years, he frequently traveled in search of a better position and composed abundantly. This situation continued until his dismissal from Salzburg in 1781 by his employer, the Prince-Archbishop, and his subsequent departure for Vienna.
