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 elements.
