Johann Georg Leopold Mozart was a German composer, violinist, and theorist. He is best known today as the father and teacher of Wolfgang Amadeus Mozart, and for his violin textbook Versuch einer gründlichen Violinschule (1756).

Wolfgang Amadeus Mozart was a prolific and influential composer of the Classical period. Despite his short life, his rapid pace of composition 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 repertoire. Mozart is widely regarded as being 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".
