Wolfgang Amadeus Mozart was a prolific and influential composer of the Classical period. Despite his short life, his rapid pace of composition and proficiency from an early age resulted in more than 800 works representing virtually every Western classical genre of his time. Many of these compositions are acknowledged as pinnacles of the symphonic, concertante, chamber, operatic, and choral repertoires. Mozart is widely regarded as one of the greatest composers in the history of Western music, with his music admired for its "melodic beauty, its formal elegance and its richness of harmony and texture".
