How do you go into the lilypond profile?
guix shell lilypond?

This sounds like gtk stuff is missing.

As a start you can use the simplest editor: nano

guix shell lilypond nano -- nano test.ly

Just edit the file there, then press CTRL-o to save and CTRL-x to exit
nano.

for starters:

# get a shell with the required programs
guix shell lilypond nano mercurial timidity++

hg clone https://hg.sr.ht/~arnebab/draketos-songbook
cd draketos-songbook
# edit the file
nano delfini-tune.ly
# create pdf and midi
lilypond delfini-tune.ly
# see the output
evince delfini-tune.pdf
# listen to it
timidity delfini-tune.midi

(that example is a song I set for my kids, so don’t expect anything fancy)

Best wishes,
Arne
