+% 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. I think this looks better in polyphonic music, when the
+% rest is below a head from a different voice.
