Sometimes it is open (like in the clefs). Sometimes % it is closed, or even a flare. % % from an email to Rune Zedeler: % % % For example, the 8th rest was vaguely based on a book with trumpet % studies by Duhem, and by Baerenreiters cello suites. I included my % findings in a comment in the mf file. One of the things that I tried % to do was make the rest a little lighter and narrower than the black % note head.
