<breath>An indication of a point at which the performer on an instrument requiring breath (including the voice) may breathe.
<measure>Unit of musical time consisting of a fixed number of note values of a given type, as determined by the prevailing meter, and delimited in musical notation by bar lines.

<nc>Sign representing a single pitched event, although the exact pitch may not be known.
<ncGrp>Collection of one or more neume components.
<neume>Sign representing one or more musical pitches.
<signifLet>Significantive letter(s).

<annot>Provides a statement explaining the text or indicating the basis for an assertion.
<arpeg>Indicates that the notes of a chord are to be performed successively rather than simultaneously, usually from lowest to highest. Sometimes called a "roll".
<beamSpan>Alternative element for explicitly encoding beams, particularly those which extend across bar lines.
<bend>A variation in pitch (often micro-tonal) upwards or downwards during the course of a note.
<bracketSpan>Marks a sequence of notational events grouped by a bracket.
<fermata>An indication placed over a note or rest to indicate that it should be held longer than its written value. May also occur over a bar line to indicate the end of a phrase or section. Sometimes called a 'hold' or 'pause'.
<gliss>A continuous or sliding movement from one pitch to another, usually indicated by a straight or wavy line.

<stageDir>Contains any kind of stage direction within a dramatic text or fragment.
<cpMark>A verbal or graphical indication to copy musical material written elsewhere.
