Ornaments and ornament lines can be applied from the Ornaments palette.
If the it is not already displayed in the palettes area, see Adding more palettes. Available ornaments include turns, (short) trills, and mordents, are discussed here. See Other lines for ornament lines available including (long) trill lines, upprall, downprall, prallprall.
To add an ornament to the score:
For a trill only, it is possible to use a custom shortcut instead at step 2.
See main chapter of ornament lines Other lines.
The procedure for applying ornament lines is just like any other line, i.e.
If you subsequently need to adjust the ornament's length, see Changing the range of a line.
Ornaments are aware of the key signature and of other accidentals in the bar. By default, trills, turns, mordents and other ornaments will display and play diatonic intervals. Use the Properties panel to change the interval, displaying the appropriate accidentals in the score and changing playback.
To change the interval of an ornament:
Trills can be customized by quality (major, minor, augmented, etc.) and interval number from unison to octave. The appropriate accidental or upper auxiliary note will display in the score above or below the ornament. For intervals larger than a second, consider using a tremolo.
Both the upper and lower interval can be set for turns.
Short trill and mordent intervals can be set to the minor or major second.
Any accidentals introduced only by an ornament must be confirmed or cancelled later in the measure for clarity, meaning it is not possible to delete accidentals where the note:
For example, in a measure starting with a chromatic turn on A as seen below, all Gs and Bs later in the measure will have an accidental, even if it is the same as what appears in the ornament.
While these accidentals cannot be deleted, their visibility can be turned off. To do so:
The following properties of selected ornaments can be edited from the Ornament section of the Properties panel:
Use the placement controls to either let MuseScore automatically choose the standard placement, or manually select above or below.
When selected, accidentals, including those linked to ornaments, have the following options in the Properties panel:
Default sizing and spacing properties for ornaments can be edited in Format→Style…→Articulations, Ornaments.
Ornaments can be individually repositioned by clicking and dragging in the score or via the Appearance dialog in the Properties panel.
