Re: Problems with music fonts

[Kevin Barry]

Hi David,

I downloaded the Beethoven font and was able to use it with your code
with LilyPond 2.22.0 on my system (Fedora 33). I don't know what the
problem is, but as you say it might be your system. If you have an older
computer to try it on, that might be a good way for you to verify.
