This is a charming (or at least, I think so) late baroque flute sonata by the little known composer Giovanni Chinzer (1700-1757). The MIDI is a fairly straightforward realization of the original. The mp3 version is me on flute with a MIDI accompaniament.
darrenwright28 What a delightful piece of music! I really enjoyed listening to it, I've listened to a few midi's on here and none of them even have a good tune. Yours sounds authentically baroque, it developes really well and such a catchy melody.
