How many piano sonata did Mozart compose?
Mozart wrote 18 complete keyboard sonatas for the “piano” of his time (which was not, strictly speaking, the modern pianoforte). There is also a traditional “19th” sonata which consist of two separate works usually performed as a complete sonata. You can find all 19 of them, chronologically, in both MIDI and MP3 form at: http://www.sdrodrian.
