mei:chord

Provides a way of pointing to a user-defined symbol. It must contain an ID
of a <symbolDef> element elsewhere in the document.

Encodes the written articulation(s). Articulations are normally encoded in
order from the note head outward; that is, away from the stem. See additional notes at
att.vis.note. Only articulations should be encoded in the artic attribute; for example,
fingerings should be encoded using the <fingering> element.

Records performed articulation that differs from the written
value.

Indicates that this event is "under a beam".

Presence of this attribute indicates that the secondary beam should be
broken following this note/chord. The value of the attribute records the number of beams
which should remain unbroken.

Indicates a single, alternative note head should be displayed instead of
individual note heads. The highest and lowest notes of the chord usually indicate the
upper and lower boundaries of the cluster note head.

Used to indicate visual appearance. Do not confuse this with the musical
term 'color' as used in pre-CMN notation.

Points to an element of which the current element is a
copy.

Used to point to other elements that correspond to this one in a generic
fashion.

Records the number of augmentation dots required by a dotted
duration.

Records the duration of a feature using the relative durational values
provided by the data.DURATION datatype.

Records performed duration information that differs from the written
duration. Its value may be expressed in several forms; that is, ppq (MIDI clicks and
MusicXML 'divisions'), Humdrum **recip values, beats, seconds, or mensural duration
values.

Records the characters often used to mark accidentals, articulations, and
sometimes notes as having a cautionary or editorial function. For an example of cautionary
accidentals enclosed in parentheses, see Read, p. 131, ex. 9-14.

Permits the current element to reference a facsimile surface or image zone
which corresponds to it.

Indicates the attachment of a fermata to this element. If visual
information about the fermata needs to be recorded, then a <fermata> element should
be employed instead.

Contains the name of a font-family.

Holds the name of a font.

Indicates the size of a font expressed in printers' points, i.e., 1/72nd
of an inch, relative terms, e.g., "small", "larger", etc., or percentage values relative
to "normal" size, e.g., "125%".

Records the style of a font, i.e, italic, oblique, or
normal.

Used to indicate bold type.

Glyph name.

Numeric glyph reference in hexadecimal notation, e.g. "#xE000" or
"U+E000". N.B. SMuFL version 1.18 uses the range U+E000 - U+ECBF.

Marks a note or chord as a "grace" (without a definitive written duration)
and records from which other note/chord it should "steal" time.

Records the amount of time to be "stolen" from a non-grace
note/chord.

Records a horizontal adjustment to a feature's programmatically-determined
location in terms of staff interline distance; that is, in units of 1/2 the distance
between adjacent staff lines.

Provides a way of pointing to a MIDI instrument definition. It must
contain the ID of an <instrDef> element elsewhere in the
document.

Provides a name or label for an element. The value may be any
string.

Identifies the layer to which a feature applies.

Indicates the attachment of an l.v. (laissez vibrer) sign to this
element.

Provides a number-like designation for an element.

Used to point to the next event(s) in a user-defined
collection.

Indicates that this element has an attached ornament. If visual
information about the ornament is needed, then one of the elements that represents an
ornament (mordent, trill, or turn) should be employed.

Points to the previous event(s) in a user-defined
collection.

Points to an element that is the same as the current element but is not a
literal copy of the current element.

Describes the relative size of a feature.

Indicates that this element participates in a slur. If visual information
about the slur needs to be recorded, then a <slur> element should be
employed.

Signifies the staff on which a notated event occurs or to which a control
event applies. Mandatory when applicable.

Describes the direction of a stem.

Encodes the stem length.

Encodes any stem "modifiers"; that is, symbols rendered on the stem, such
as tremolo or Sprechstimme indicators.

Records the position of the stem in relation to the note
head(s).

Contains an indication of which staff a note or chord that logically
belongs to the current staff should be visually placed on; that is, the one above or the
one below.

Records the output x coordinate of the stem's attachment
point.

Records the output y coordinate of the stem's attachment
point.

Holds an associated sung text syllable.

Points to elements that are synchronous with the current
element.

Indicates that this element participates in a tie. If visual information
about the tie needs to be recorded, then a <tie> element should be
employed.

Records a timestamp adjustment of a feature's programmatically-determined
location in terms of musical time; that is, beats.

Encodes the onset time in terms of musical time, i.e.,
beats[.fractional_beat_part].

Captures performed onset time in several forms; that is, ppq (MIDI clicks
and MusicXML 'divisions'), Humdrum **recip values, beats, seconds, or mensural duration
values.

Used to record the onset time in terms of ISO time.

Indicates that this feature participates in a tuplet. If visual
information about the tuplet needs to be recorded, then a <tuplet> element should be
employed.

Indicates if a feature should be rendered when the notation is presented
graphically or sounded when it is presented in an aural form.

Indicates the point of occurrence of this feature along a time line. Its
value must be the ID of a when element elsewhere in the document.

Encodes an x coordinate for a feature in an output coordinate system. When
it is necessary to record the placement of a feature in a facsimile image, use the facs
attribute.

Provides a base URI reference with which applications can resolve relative
URI references into absolute URI references.

Regularizes the naming of an element and thus facilitates building links
between it and other resources. Each id attribute within a document must have a unique
value.

Encodes an y coordinate for a feature in an output coordinate system. When
it is necessary to record the placement of a feature in a facsimile image, use the facs
attribute.
