+% Notes about 8th rest:
+%
+% * 8th rest should be no wider than the black note head
+%
+% * The inside corner of the horizontal portion is usually a little blotted.
+%
+% * The top of the crook chops off the vertical brush
+%
+% * The crook widens a little
+%
+% * The bottom of the brush is slightly flat, as it has to align with
+% stafflines if it is inside the staff.
+%
+% * The top of the brush usually is a little lower than the top of bulb.
+%
+% * The bulb can vary. 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. I think this looks better in polyphonic music, when the
+% rest is below a head from a different voice.
