Musipedia is a searchable, editable, and expandable collection of tunes, melodies, and musical themes. Entries 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. Musipedia uses the "Melodyhound" melody search engine. You can find and identify a tune even if the melody is all you know. You can play it on a piano keyboard, whistle it to the computer, simply tap the rhythm on the computer keyboard or use the Parsons code.
