I was thinking of something like this:

That is, simultaneously: a) play a note, b) wait a short while, reduce volume, wait until rest of the note is finished (2.. is 7/8 of a measure), then reset to normal.

Thank you, perfect!!!!

In case other people need it, here it is a complete example where c1 note is played reducing volume from maximum to minimum in step of 1/32.

\version "2.19.80"

right = \fixed c'' { c1 }

dynamics = {
