The included file guitar.ly is missing. It might not be strictly required
but I thought I’d mention it.
Right, guitar.ly is slightly scary (see below) and might not be used. Again it
may not build with newer lilypond.
Basically, I got pulled away from my guitars about 5+ years ago by life. I can't
even remember which end to blow into. 8-(
I attached a PDF of O Canada.
Oh, and I attached something I was working on and never finished. Some of it is
rubbish and needs people with more knowledge than me to get right. I may have
posted it to lilypond in the past, so sorry if this is a repeat.
