Hamelin's infamous etude dedicated to the father of harpsichord sonatas.
NB: While the tempo on the sheet music is at 90 to 100 quarter notes per minute, I adjusted the speed to 144 to roughly match the speed of the composer's performance of the etude, which you can view here: http://www.youtube.com/watch?v=DiQJwcYiTWg
It should be noted that the second part of the piece should be repeated, however, the composer in the video did not follow the repeat.
I do NOT guarantee that this MIDI file has no errors; I do NOT own this piece either.
