I'm writing a timpani part for a concert band score. I've seen timpanist "choke" the note with their hand (on the head) after striking it to stop it from sustaining. How can I notate this?
There are several symbols at my favorite reference such as "+" which indicate percussion instrument damping. I plead ignorance as to which symbols are applied to the tympani in particular. Search the linked page for the word "damp," and you'll see a couple crosshair-like symbols, sadly without comments as to applicability.
