I have a very handy music function for that (based on an idea by David K.):
after =
#(define-music-function (t e m) (ly:duration? ly:music? ly:music?)
#{
<<
#m
{ \skip $t <> -\tweak extra-spacing-width #empty-interval $e }
>>
#})
With that you can write things like:
\new Voice {
\after 2. \> dis1\< <>\! |
\after 4 \< \after 2 \> \after 2. \p dis1
\after 2. \stopTrillSpan dis1\startTrillSpan
\after 2 \upbow dis1\downBow
}
Note that it’s essential to explicitly create the voice with \new
Voice, else the <<>> in the music function will create new voices and
it won’t work.
Any reason you are not writing
\context Bottom << ... >>
here? I seem to remember suggesting that in some discussion (maybe a
different one?) but have no idea any more whether it might have posed a
separate problem at that time.
Oh, interesting idea! Never heard of. It seems like a fine and sensible
thing to do, except that normally I would have created the voices
explicitly in my score block, and I am using \context only when
referencing already existing contexts – isn’t that kind of a policy? But
I see, you probably mean putting it inside the music function:
after =
#(define-music-function (t e m) (ly:duration? ly:music? ly:music?)
#{
\context Bottom <<
#m
{ \skip $t <> -\tweak extra-spacing-width #empty-interval $e }
>>
#})
There’s nothing wrong with that, and it prevents any problems indeed.
Thanks,
Simon
