+If you have more than one voice on the staff, setting octavation in one
+voice will transpose the position of notes in all voices for the
+duration of the ottava bracket. If the ottavation is only intended to
+apply to one voice, the middleCPosition and ottava bracket may be set
+explicitly.  In this snippet, the bass clef usually has middleCPosition
+set to 6, six positions above the center  line, so in the 8va portion
+middleCPosition is 7 positions (one octave) higher still.
