(MEI.harmony) Groups harmonic elements that function as control events; that is, those
events that modify or otherwise depend on the existence of notated events.
(MEI.shared) Groups elements, such as dynamics, ties, phrase marks, pedal marks, etc.,
which depend upon other events, such as notes or rests, for their existence.
(MEI.cmn) Groups elements that may appear within a CMN measure.
