Back in June, I was typing up some Aiken-heads music for a client. We
ran into a problem shown in the attached PNG and LY files, where
white-head notes end up too dark at lower staff sizes. The problem was
resolved by using thin-variant Aiken heads. However, arriving at that
solution was a little challenging. With web searches, I was able to find
that the thin-variant note heads existed, but not how to access them. A
post to lilypond-user got good help from Abraham Lee.
https://lists.gnu.org/archive/html/lilypond-user/2017-06/msg00137.html
The solution was:
aikenHeadsThin = \set shapeNoteStyles = ##(doThin reThin miThin faThin
sol laThin tiThin)
Now I am wondering about having this information posted somewhere more
prominently. I understand the options could be...
a snippet for the LSR,
a reference in the documentation, perhaps under NR 1.1.4 Shape note heads,
adding a feature to LilyPond, the command \aikenHeadsThin
Any preference from the developers? I've read some of the contributor's
guide, and doing the work looks like a fun challenge.
