dir

<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>.

Attributes


@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.

@place(optional)Captures the placement of the item with respect to the staff with which it is associated. Value conforms to data.STAFFREL. att.placement
@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

Remarks

Examples include text strings, such as 'affettuoso', and music symbols, such as segno and coda symbols, fermatas over a bar line, etc. Directives can be control elements. That is, they can linked via their attributes to other events. The starting point of the directive 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 a starting point attribute.

Constraint

Must have one of the attributes: startid, tstamp, tstamp.ges or tstamp.real.
