Denemo helps prepare notation for publishing and lets a user rapidly enter notation, simultaneously typesetting via the LilyPond music engraver. Music can be typed in using a PC keyboard, taken from [[MIDI]] input, or played into a microphone plugged into a [[soundcard]]. The program plays back via an internal [[Sampler (musical instrument)|sampler]] and can act as a [[JACK Audio Connection Kit|JACK]]/MIDI client. Denemo includes scripts to run music tests and practice exercises for educational purposes.
