GNU Denemo
Graphical music notation, front-end to GNU Lilypond

Denemo is a music notation editor that provides a convenient interface to the powerful music engraving program Lilypond. Music can be typed in using the computer keyboard, played in using a MIDI keyboard, or even input via a microphone connected to the sound card.

Denemo itself does not engrave the music - it uses LilyPond which generates beautiful sheet music to the highest publishing standards. The final product is publication-quality music notation that is continuously generated in the background.
