Hi Kieren,
Specifiying the context name is easy, that’s just a markup:
toDyn =
#(define-music-function (music1 music2 context) (ly:music? ly:music? markup?)
#{
<< #music1 \new Container \new Notes { \change Container = #context
#music2 } >>
#})
For the other thing I do not think it is possible. Tweaking would tweak a
property of the music, and Lilypond only allows for post events, but not for
postscript functions. So I do no think it would be possible to get both music
parts into parallel.
Valentin
