<beamSpan>

<beamSpan> (beam span) – Alternative element for explicitly encoding beams, particularly those which extend across bar lines.
Module MEI.cmn
Attributes
@beam.with (optional) In the case of cross-staff beams, the beam.with attribute is used to indicate which staff the beam is connected to; that is, the staff above or the staff below. Value conforms to data.OTHERSTAFF . att.beamedwith
@color (optional) Used to indicate visual appearance. Do not confuse this with the musical term 'color' as used in pre-CMN notation. Value conforms to data.COLOR . att.color
@copyof (optional) Points to an element of which the current element is a copy. Value conforms to data.URI . att.common.anl
@corresp (optional) Used to point to other elements that correspond to this one in a generic fashion. One or more values from data.URI , separated by spaces. att.common.anl
@dots (optional) Records the number of augmentation dots required by a dotted duration. Value conforms to data.AUGMENTDOT . att.augmentdots
@dur (optional) Records duration using optionally dotted, relative durational values provided by the data.DURATION datatype. When the duration is "irrational", as is sometimes the case with tuplets, multiple space-separated values that add up to the total duration may be used. When dotted values are present, the dots attribute must be ignored. One or more values from data.DURATION.additive , separated by spaces. att.duration.additive
@dur.ges (optional) 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. Value conforms to data.DURATION.gestural . att.duration.performed
@endid (optional) Indicates the final element in a sequence of events to which the feature applies. Value conforms to data.URI . att.startendid
@evaluate (optional) Specifies the intended meaning when a participant in a relationship is itself a pointer. Allowed values are: " all" (If an element pointed to is itself a pointer, then the target of that pointer will be taken, and so on, until an element is found which is not a pointer.) , " one" (If an element pointed to is itself a pointer, then its target (whether a pointer or not) is taken as the target of this pointer.) , " none" (No further evaluation of targets is carried out beyond that needed to find the element(s) specified in plist or target attribute.) att.targeteval
@facs (optional) Permits the current element to reference a facsimile surface or image zone which corresponds to it. One or more values from data.URI , separated by spaces. att.facsimile
@form (optional) Captures whether a beam is "feathered" and in which direction. Allowed values are: " acc" ((accelerando) indicates that the secondary beams get progressively closer together toward the end of the beam.) , " mixed" ((mixed acc and rit) for beams that are "feathered" in both directions.), " rit" ((ritardando) means that the secondary beams become progressively more distant toward the end of the beam.) , " norm" ((normal) indicates that the secondary beams are equidistant along the course of the beam.) att.beamrend
@label (optional) Provides a name or label for an element. The value may be any string. Value of datatype string. att.commonPart
@layer (optional) Identifies the layer to which a feature applies. One or more values of datatype positiveInteger, separated by spaces. att.layerident
@n (optional) Provides a number-like designation for an element. Value conforms to token . att.common
@next (optional) Used to point to the next event(s) in a user-defined collection. One or more values from data.URI , separated by spaces. att.common.anl
@plist (optional) 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". One or more values from data.URI , separated by spaces. att.plist
@prev (optional) Points to the previous event(s) in a user-defined collection. One or more values from data.URI , separated by spaces. att.common.anl
@sameas (optional) Points to an element that is the same as the current element but is not a literal copy of the current element. One or more values from data.URI , separated by spaces. att.common.anl
@slope (optional) Records the slope of the beam. Value of datatype decimal. att.beamrend
@staff (optional) Signifies the staff on which a notated event occurs or to which a control event applies. Mandatory when applicable. One or more values of datatype positiveInteger, separated by spaces. att.staffident
@startid (optional) Holds a reference to the first element in a sequence of events to which the feature applies. Value conforms to data.URI . att.startid
@subtype (optional) Provide any sub-classification for the element, additional to that given by its type attribute. Value of datatype NMTOKEN. att.typed
@synch (optional) Points to elements that are synchronous with the current element. One or more values from data.URI , separated by spaces. att.common.anl
@tstamp (optional) Encodes the onset time in terms of musical time, i.e., beats[.fractional_beat_part]. Value conforms to data.BEAT . att.timestamp.musical
@tstamp.ges (optional) Captures performed onset time in several forms; that is, ppq (MIDI clicks and MusicXML 'divisions'), Humdrum **recip values, beats, seconds, or mensural duration values. Value conforms to data.DURATION.gestural . att.timestamp.performed
@tstamp.real (optional) Used to record the onset time in terms of ISO time. Value conforms to data.ISOTIME . att.timestamp.performed
@tstamp2 (optional) Encodes the ending point of an event in terms of musical time, i.e., a count of measures plus a beat location. Value conforms to data.MEASUREBEAT . att.timestamp2.musical
@type (optional) Characterizes the element in some sense, using any convenient classification scheme or typology. Value of datatype NMTOKEN. att.typed
@when (optional) 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. Value conforms to data.URI . att.alignment
@xml:base (optional) Provides a base URI reference with which applications can resolve relative URI references into absolute URI references. Value conforms to data.URI . att.commonPart
@xml:id (optional) 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. Value of datatype ID. att.id

Remarks

The starting point of the beam may be indicated by either a startid, tstamp, tstamp.ges, or tstamp.real attribute, while the ending point may be recorded by either a dur, dur.ges, endid, or tstamp2 attribute. It is a semantic error not to specify one starting and one ending type of attribute.

Constraints
Must have one of the attributes: startid, tstamp, tstamp.ges or tstamp.real.
Must have one of the attributes: dur, dur.ges, endid, or tstamp2.
