The beam sub-element is allowed so that custom beaming may be indicated, e.g., a septuplet may be divided into a group of three plus a group of four notes. See Read, p. 187-215. The tuplet element may also used for bowed tremolo (Read, p. 394) and double, triple, or flutter tonguing (Read, p. 348-349); that is, for repetition of the same pitch. In the case of irrational durations, such as such as two quarter notes in the time of five 8th notes in a measure of 5/8 time, decimal values may be used in the dur.ges attribute. For example, the dur.ges attribute would take the value 2.5 if the midi.div attribute’s value was 1. The num and numbase attributes may be used for explicit labelling of a tuplet, such as, '3' with an 8th-note triplet, '3:2' over a quarter-note triplet, etc. The rendering of the ratio, however, is dependent on the num.format attribute found in the att.vis.tuplet attribute class.
