Music began to be a major part of city life in the middle of the 18th century. Organs began to appear in non-Quaker churches and the city staged its first opera, "The Beggar's Opera". The city's musical scene grew in the 19th century with the music of William Henry Fry, and the founding of the Musical Fund Society which began underwriting concerts in 1820. The Musical Fund Society begat the Academy of Music in 1857, which now hosts the Philly Pops, the Pennsylvania Ballet and the Opera Company of Philadelphia.
