Lilypond music fonts have got sizes in the filenames. Like emmentaler-18.otf,
emmentaler-20.otf, ... And they also have the brace like emmentaler-brace.otf,
though not all fonts have got the brace. Gonville is a lilypond font. The fonts
from github made by Abraham are lilypond fonts, i don't believe he had any
smufl ones for free, smufl came later(?). MTF sold some fonts as only smufl,
while some were also available as lilypond versions iirc. I'm not sure what
versions you may have downloaded/bought. Check the filenames
