Yesterday during #homeschool computer class, we started learning how to use the music engraving program #lilypond.
We began by going through the lilypond tutorials at: https://www.youtube.com/watch?v=tclwyZr08bE&list=PLHi8BvxILUV6x9FqEmZiYrEj6VMGmTKjt
At first, we were writing the score in emacs, but then we installed frescobaldi to use as a minimal GUI. Really nice piece of software!
My son is really into playing along with #midi files on the #piano, so he wanted to generate midi output from lilypond.
One of the issues we encountered was connecting timidity to the midi output port. We ended up using the method here to start timidity as an ALSA sequencer client (without blocking all other audio playback system-wide):

After that, we were able to play the music via midi output using the following lilypond example:
