I bought a copy of the sheet music for this piece then input the notes into Sibelius. A MIDI file was then exported from Sibelius and imported into Reason. From there I added a couple of effects and tweaked the MIDI data a little bit. The pics are scanned copies of the sheet music set to a transparent Mozart background.
This is a school project I was assigned. The purpose was to create an audio piece that had no rhythmic value or meter. Used Protools and Reason with a keyboard controller.
