I understand. My expectation was that \tripletFeel would know about the
\partial measure at the beginning of the piece and figure out the offset
automatically, but that is not the case. Unfortunately in my application
the \tripletFeel is applied in a file separate from the music definition.
It looks like I will have to figure out a way to pass that offset as a
parameter, unless there is a way to examine the music object to determine
if it has a partial measure at the beginning.
