Since not all instruments are percussive (like a piano is), it would
make sense to also (optionally?) encode dynamic changes during note
duration as "expression" signals.  Otherwise a crescendo on sustained
notes (like a string instrument or a wind instrument or an accordion can
deliver) will not happen.
