Available at
breath(breath mark) – An indication of a point at which the performer on an instrument requiring breath (including the voice) may breathe.
measureUnit 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.
reh(rehearsal mark) – In an orchestral score and its corresponding parts, a mark indicating a convenient point from which to resume rehearsal after a break.
episemaEpisema.
hispanTickHispanic tick.
ncSign representing a single pitched event, although the exact pitch may not be known.
ncGrpCollection of one or more neume components.
neumeSign representing one or more musical pitches.
signifLetSignificantive letter(s).
syllableNeume notation can be thought of as "neumed text". Therefore, the syllable element provides high-level organization in this repertoire.
annot(annotation) – Provides a statement explaining the text or indicating the basis for an assertion.
arpeg(arpeggiation) – 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(beam span) – Alternative element for explicitly encoding beams, particularly those which extend across bar lines.
bendA variation in pitch (often micro-tonal) upwards or downwards during the course of a note.
bracketSpanMarks a sequence of notational events grouped by a bracket.
fermataAn 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(glissando) – A continuous or sliding movement from one pitch to another, usually indicated by a straight or wavy line.
hairpinIndicates continuous dynamics expressed on the score as wedge-shaped graphics, e.g. < and >.
harpPedal(harp pedal) – Harp pedal diagram.
lvA "tie-like" indication that a note should ring beyond its written duration.
octaveAn indication that a passage should be performed one or more octaves above or below its written pitch.
pedalPiano pedal mark.
slurIndication of 1) a "unified melodic idea" or 2) performance technique.
tieAn indication that two notes of the same pitch form a single note with their combined rhythmic values.
tupletSpan(tuplet span) – Alternative element for encoding tuplets, especially useful for tuplets that extend across bar lines.
mordentAn ornament indicating rapid alternation of the main note with a secondary note, usually a step below, but sometimes a step above.
trillRapid alternation of a note with another (usually at the interval of a second above).
turnAn ornament consisting of four notes — the upper neighbor of the written note, the written note, the lower neighbor, and the written note.
sp(speech) – Contains an individual speech in a performance text.
stageDir(stage direction) – Contains any kind of stage direction within a dramatic text or fragment.
cpMark(copy/colla parte mark) – A verbal or graphical indication to copy musical material written elsewhere.
metaMarkA graphical or textual statement with additional / explanatory information about the musical text. The textual consequences of this intervention are encoded independently via other means; that is, with elements such as <add>, <del>, etc.
fingfinger – An individual finger in a fingering indication.
fingGrp(finger group)– A group of individual fingers in a fingering indication.
f(figure) – Single element of a figured bass indication.
harm(harmony) – An indication of harmony, e.g., chord names, tablature grids, harmonic analysis, figured bass.
accid(accidental) – Records a temporary alteration to the pitch of a note.
artic(articulation) – An indication of how to play a note or chord.
attaccaAn instruction to begin the next section or movement of a composition without pause.
dir(directive) – An instruction expressed as a combination of text and symbols — such as segno and coda symbols, fermatas over a bar line, etc., typically above, below, or between staves, but not on the staff — that is not encoded elsewhere in more specific elements, like tempo or dynam.
dotDot of augmentation or division.
dynam(dynamic) – Indication of the volume of a note, phrase, or section of music.
ornamAn element indicating an ornament that is not a mordent, turn, or trill.
phraseIndication of 1) a "unified melodic idea" or 2) performance technique.
tempoText and symbols descriptive of tempo, mood, or style, e.g., "allarg.", "a tempo", "cantabile", "Moderato", "♩=60", "Moderato ♩ =60").
lineA visual line that cannot be represented by a more specific; i.e., semantic, element.
mdiv(musical division) – Contains a subdivision of the body of a musical text.
endingAlternative ending for a repeated passage of music; i.e., prima volta, seconda volta, etc.
clefIndication of the exact location of a particular note on the staff and, therefore, the other notes as well.
clefGrp(clef group) – A set of simultaneously-occurring clefs.
beamA container for a series of explicitly beamed events that begins and ends entirely within a measure.
beatRpt(beat repeat) – An indication that material on a preceding beat should be repeated.
bTrem(bowed tremolo) – A rapid alternation on a single pitch or chord.
fTrem(fingered tremolo) – A rapid alternation between a pair of notes (or chords or perhaps between a note and a chord) that are (usually) farther apart than a major second.
graceGrpA container for a sequence of grace notes.
halfmRpt(half-measure repeat) – A half-measure repeat in any meter.
mRest(measure rest) – Complete measure rest in any meter.
mRpt(measure repeat) – An indication that the previous measure should be repeated.
mRpt2(2-measure repeat) – An indication that the previous two measures should be repeated.
mSpace(measure space) – A measure containing only empty space in any meter.
multiRest(multiple rest) – Multiple measures of rest compressed into a single symbol, frequently found in performer parts.
multiRpt(multiple repeat) – Multiple repeated measures.
tupletA group of notes with "irregular" (sometimes called "irrational") rhythmic values, for example, three notes in the time normally occupied by two or nine in the time of five.
chordA simultaneous sounding of two or more notes in the same layer *with the same duration*.
noteA single pitched event.
pad(padding) – An indication of extra visual space between notational elements.
restA non-sounding event found in the source being transcribed.
spaceA placeholder used to fill an incomplete measure, layer, etc. most often so that the combined duration of the events equals the number of beats in the measure.
pb(page beginning) – An empty formatting element that forces text to begin on a new page.
sb(system beginning) – An empty formatting element that forces musical notation to begin on a new line.
sectionSegment of music data.
breath(breath mark) – An indication of a point at which the performer on an instrument requiring breath (including the voice) may breathe.
