Denemo is a music notation program for Linux and Windows that lets you rapidly enter notation for typesetting via the LilyPond music engraver. Music can be typed in at the PC-Keyboard, or played into a microphone plugged into your computer's soundcard.

Denemo itself does not engrave the music - it uses LilyPond which generates beautiful sheet music to the highest publishing standards. Denemo just displays the music so you can enter and edit the music efficiently.

Features:

• Logically arranged menus to locate any particular command - once found the keypress is displayed with the command.
• Complete, quick and easy control over which keypress to use for any particular Denemo command.
• Help for every command on the menu item itself - just right click. Playing back your music while the measures scroll on the screen. Midi output.
• PDF output, with a choice of parts, full score, reduced score - all the control that the LilyPond language supplies. Output of excerpts as graphics (.png format) for inclusion in documents, web pages etc.
• Multiple movements/songs in one Denemo file.
• Entering music following rhythmic patterns - type in the rhythm once and you need only type in the notes in future when the same rhythm recurs.
• Playing music in via microphone - the notes played are detected and entered according to the prevailing rhythm, or overlaying a rhythm previously entered.
• Files of Templates and Examples showing you how to exploit LilyPond features. An extreme example - a cue in one part extracted from another part. Should you edit the first part, the cue changes automatically! As usual, Denemo does not display the cue, only a sign telling you what LilyPond is doing.
• A musical instrument tuner - in fact, probably the best. Temperaments include mean-tone and the Lehman temperament for J.S. Bach.
