You can also write the tempo markings in the same place as the music but
use \omit to make them invisible in the printed score.

OTOH, it would be nice if we could come up with a clever Scheme function
that automates ramping the tempo down/up; it's rather tedious to insert
all those \tempo markings by hand.
