code to instruct a swell for the duration of c2
There’s several possibilities:
First, LilyPond has the built-in command \espressivo (which is
technically not a dynamic script, but an articulation):
%%%%%%
{ c2\espressivo }
%%%%%%
Second, your ‘example’ hints at this strategy:
%%%%%%
\context Voice <<
{ c2 }
{ s4\< s\> <>\! }
>>
%%%%%%
Third, you could use this:
%%%%%%
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 }
>>
#})
{ \after 8. \> \after 4. \! c2\< }
%%%%%%%
It’s up to you which you prefer.
Best,
Simon
