183 % Notes about 8th rest:
185 % * 8th rest should be no wider than the black note head
187 % * The inside corner of the horizontal portion is usually a little blotted.
189 % * The top of the crook chops off the vertical brush
191 % * The crook widens a little
193 % * The bottom of the brush is slightly flat, as it has to align with
194 % stafflines if it is inside the staff.
196 % * The top of the brush usually is a little lower than the top of bulb.
198 % * The bulb can vary. Sometimes it is open (like in the clefs). Sometimes
199 % it is closed, or even a flare.
