Re: Duration shortcut not working for rests
Ah, that makes sense. I can see how the behavior would be useful there.
I think part of the surprise is that when writing \new Dynamics voices I
will only use spacer rests, and typically only specify the "s" the first
time, leaving the rest of the piece described with just durations.
\new Dynamics {
s1
| 2\< 2\>
| 1\!
}
But if I try to use spacer rests in a musical context with pitches, then
the compiler stops remembering the "s".
\version "2.25.6"
{
c'4 4 4 4
% These are still "c"s
| s4 4 4 4
}
Would it be reasonable for this to be configurable, so that different parts
could remember or forget rests as needed?

It's on purpose (even though I tend to agree that it is a bit quirky). One
reason is to simplify the writing of percussion lines, where the same drum name
is often repeated over and over, mixed with rests.

Part of what may be confusing me is that when defining a \new Dynamics
voice, I will use only spacer rests, and I typically only specify the
first "s", leaving only the durations for the rest of the piece. For
example...
\new Dynamics {
s1
| 1
| 2\< 2\>
| 1\!
}
Yet, if I try similar in a music expression with pitches, it refuses to
remember the spacers.
\version "2.25.6"
{
c'4 4 4 4
% These 4s are "c"s instead of rests
| r4 4 4 4
% These are still "c"s
| s4 4 4 4
}
The behavior changed. Why?

Hi William,
If you want to write more rests, the syntax is

Much like

Lilypond remembers the duration, but needs to know what to print
with that duration.
