David,
I'm sorry to say that I'm unable to figure this out on my own.
\applyMusic is completely undocumented and the few occurrences in the
source code are not illustrative enough for me.  Within an \applyMusic
construct, how do I access a given grob-property value, and then
override it -- temporarily?

Thanks.
