I think it's a bit hard to do in Scheme (need to do look-ahead in the list
of chords).

What I'd like to see is a general rubato function, that:
  1. takes a parameter (maybe call it `swing') that lengthens on-beat
     phrases, and shortens off-beat phrases by the same amount (so convert
     a8 b to \times 2/3 { a4 b8 } or { a8 b16 c } to \times 2/3 {a4 b16 c}
     or similar)
  2. Within phrasing slurs does a slight accelerando into the phrase
     and a slight decelerando to a-tempo at the end
