mei:tempo

Contains a reference to a field or element in another descriptive encoding
system to which this MEI element is comparable.

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 horizontal adjustment of a feature's
programmatically-determined end point.

Records a timestamp adjustment of a feature's programmatically-determined
end point.

Specifies the intended meaning when a participant in a relationship is
itself a pointer.

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

Records the function of a tempo indication.

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

Identifies the layer to which a feature applies.

Captures the number of *quarter notes* per minute. In MIDI, a beat is
always defined as a quarter note, *not the numerator of the time signature or the
metronomic indication*.

Records the number of microseconds per *quarter note*. In MIDI, a beat is
always defined as a quarter note, *not the numerator of the time signature or the
metronomic indication*. At 120 quarter notes per minute, each quarter note will last
500,000 microseconds.

Used to describe tempo in terms of beats (often the meter signature
denominator) per minute, ala M.M. (Maezel's Metronome). Do not confuse this attribute with
midi.bpm or midi.mspb. In MIDI, a beat is always defined as a quarter note, *not the
numerator of the time signature or the metronomic indication*.

Records the number of augmentation dots required by a dotted metronome
unit.

Captures the metronomic unit.

Provides a number-like designation for an element.

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

Captures the placement of the item with respect to the staff with which it
is associated.

Contains a space separated list of references that identify active
participants in a collection/relationship, such as notes under a phrase mark; that is, the
entities pointed "from".

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.

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

Records the horizontal adjustment of a feature's
programmatically-determined start point.

Holds a reference to the first element in a sequence of events to which
the feature applies.

Records a timestamp adjustment of a feature's programmatically-determined
start point.

Provide any sub-classification for the element, additional to that given
by its type attribute.

Points to elements that are synchronous with the current
element.

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

Specifies the transliteration technique used.

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.

Characterizes the element in some sense, using any convenient
classification scheme or typology.

Records the vertical adjustment of 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.

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.

Identifies the language of the element's content. The values for this
attribute are language 'tags' as defined in BCP 47. All language tags that make use of
private use sub-tags must be documented in a corresponding language element in the MEI
header whose id attribute is the same as the language tag's 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.
