Re: Instrument name disappears if I start it with a grace note
That makes sense. I'll try to stick with the \with notation whenever
possible.
Thanks for the clear explanation.

You start _simultaneous_ music on a new Staff (that's what <<...>>
does). That means that all the parallel music starts on the first beat
with the exception of grace notes. The only grace note is b16, and
LilyPond needs to create the Staff for placing it anywhere. Then, on
the first beat, it typesets both the c1 and executes the \set
Staff.instrumentName command which comes too late to affect the Staff
that already needed to be created for the sake of the appoggiatura. As
Knute stated, for settings supposed to be an unchanging part of some
context, it makes more sense to establish them in a \with block rather
than inside of the context after it has already started. Instrument
names certainly belong in that category.

Hi Knute, >> It's still interesting to see why it happens, and document it if it is the >> expected behavior. > I'm guessing that it has to do with LilyPond's most famous bug, issue #34: > https://gitlab.com/lilypond/lilypond/-/issues/34 Yep. \with happens before the first actual score moment, which is where the bug officially "starts". There are several Lilypond behaviour issues that I get around by using \with (and then \undo, if necessary).

Re: Instrument name disappears if I start it with a grace note
Thank you! It does work.
It's still interesting to see why it happens, and document it if it is the
expected behavior.

I don't know why it works, but try this:
%%%
\version "2.22.1"
\score {
\new Staff \with { instrumentName = \markup \bold "Name" } <<
\context Voice = "voice" \relative c'' { \appoggiatura b16 c1 }
>>
}
%%%

Instrument name disappears if I start it with a grace note
Hello all.
I think I just described the problem in the title, but it only happens if I
have a multi-voice staff, as the following example demonstrates:
%%%
\version "2.22.1"
\score {
\new Staff <<
\set Staff.instrumentName = \markup \bold "Name"
\context Voice = "voice" \relative c'' { \appoggiatura b16 c1 }
>>
}
%%%
The name appears if one removes the beginning appoggiatura. It works with
grace, slashedGrace, and acciaccatura too.
Thanks in advance,
Omid Momenzadeh
