This has the potential to be quite cool–Musipedia:
Inspired by, but not affiliated with Wikipedia, we are building a searchable, editable, and expandable collection of tunes, melodies, and musical themes.
Every entry can be edited by anybody. An entry can contain a bit of sheet music, a MIDI file, textual information about the work and the composer, and last but not least the Parsons Code, a rough description of the melodic contour, to make the encyclopedia searchable by melody.
