Beam

class music21.musicxml.mxObjects.Beam

Beams are specified is individual objects for each beam, in order, where the beam number refers to its duration representation (8th, 16th, etc) and its character data specifies whether it is begin/continue/end (for normal beams) or backward hook/forward wook (for beams that do not continue are attached only to the staff). These character data values can be mixed: one beam can continue while another can hook or end.

1 = 8th 2 = 16th 3 = 32th 4 = 64th 5 = 128th 6 = 256th

From musicxml.xsd:

Beam values include begin, continue, end, forward hook, and backward hook. Up to six concurrent beam levels are available to cover up to 256th notes. The repeater attribute, used for tremolos, needs to be specified with a “yes” value for each beam using it. Beams that have a begin value can also have a fan attribute to indicate accelerandos and ritardandos using fanned beams. The fan attribute may also be used with a continue value if the fanning direction changes on that note. The value is “none” if not specified.

Note that the beam number does not distinguish sets of beams that overlap, as it does for slur and other elements. Beaming groups are distinguished by being in different voices and/or the presence or absence of grace and cue

Tag

class music21.musicxml.mxObjects.Tag(tag, cdFlag=False, className=None)

Object to store tags as encountered by SAX. Tags can be open or closed based on the status attribute. Tags can store character data collected between their defined tags.

These objects are used only for finding and collecting tag attributes and elements. As we do not need character data for all tags, tags have an optional flag to select if the are to collect character data.

TagLib

class music21.musicxml.mxObjects.TagLib

An object to store all MusicXML tags as Tag objects. Tag objects are used just to identify tags, store element contents and status in SAX parsing.

With this design some tags (called simple elements) can be used simply in SAX parsing as structural monitors, but not be instantiated as objects for content delivery.

TagLib methods

TagLib.audit()

A way to check for errors in SAX parsing. Assumes that all start() calls have been paired with an end() call, and that all element data has been cleared.

TagLib.getClassName(key)

Get the class or name, or None if none defined.

>>> tl = musicxml.mxObjects.TagLib()
