The <tremolo> element

Parent element: <ornaments>

The tremolo ornament can be used to indicate single-note, double-note, or unmeasured tremolos. Single-note tremolos use the single type, double-note tremolos use the start and stop types, and unmeasured tremolos use the unmeasured type. The default is “single” for compatibility with Version 1.1. The text of the element indicates the number of tremolo marks and is an integer from 0 to 8. Note that the number of attached beams is not included in this value, but is represented separately using the beam element. The value should be 0 for unmeasured tremolos.

When using double-note tremolos, the duration of each note in the tremolo should correspond to half of the notated type value. A time-modification element should also be added with an actual-notes value of 2 and a normal-notes value of 1. If used within a tuplet, this 2/1 ratio should be multiplied by the existing tuplet ratio.

The smufl attribute specifies the glyph to use from the SMuFL Tremolos range for an unmeasured tremolo. It is ignored for other tremolo types. The SMuFL buzzRoll glyph is used by default if the attribute is missing.

Using repeater beams for indicating tremolos is deprecated as of MusicXML 3.0.
