% Each clef is associated with a particular pitch: the treble clef
-% with the 'g', the alto clef with the 'c', the bass clef with the
-% 'f', etc. The shape of each clef character defines a vertical
+% with the `g', the alto clef with the `c', the bass clef with the
+% `f', etc. The shape of each clef character defines a vertical
% position that is assumed to represent this pitch. For the treble
% clef, it is the vertical position of the center of the spiral
-% ending that represents the 'g' pitch. For the bass clef, it is
+% ending that represents the `g' pitch. For the bass clef, it is
% the center between the two fat dots that define the vertical
-% position of the 'f' pitch. For the alto clef, it is the vertical
-% center of the clef that is aligned with the 'c' pitch. For each
+% position of the `f' pitch. For the alto clef, it is the vertical
+% center of the clef that is aligned with the `c' pitch. For each
% clef character, this center should be vertically aligned with the
% point (0, 0). The horizontal alignment of each clef character
% should be such that the vertical line through the point (0, 0)
