While none of these genres were new, the piano concerto was almost single-handedly developed and popularized by Mozart. In addition, he was a versatile composer and wrote in almost every major genre, including symphony, opera, the solo concerto, chamber music including string quartet and string quintet, and the piano sonata. Mozart's own stylistic development closely paralleled the development of the classical style as a whole.

His works spanned the period during which that style transformed from one exemplified by the style galant to one that began to incorporate some of the contrapuntal complexities of the late Baroque, complexities against which the galant style had been a reaction.

Mozart's music, like Haydn's, stands as an archetypal example of the Classical style.
