An accidental is a sign appearing in front of a note that raises or lowers its pitch. Musescore creates playback for common accidentals only, they includes 7 accidentals: b (flat), ♮ (natural), # (sharp), x (double sharp), bb (double flat), #x (triple sharp), bbb (triple flat). To create microtonal accidentals such as quarter tone, see Tuning systems, microtonal notation system, and playback Chapter.
Accidentals affect all notes on the same staff position only for the remainder of the measure in which they occur, but they can be canceled by another accidental. In notes tied across a barline, the accidental continues across the barline to the tied note, but not to later untied notes on the same staff position in that measure.
Accidentals are automatically added, replaced or removed when note's pitch changes:
To add directly either (i) a bb double flat or x double sharp, (ii) a courtesy (also known as cautionary or reminder) accidental, or (iii) a non-standard accidental, use one of the following options:
Add from Accidentals category of the Master palette using the select and click or drag and drop method. Do not add from Symbols category, they are non-functional visual symbols, see Notation types.
In the above diagram, the second accidental is added from Symbols category of the Master palette, it does not use automatic layout and the note pitch does not change (C instead of C#).
To add brackets (only available for courtesy/cautionary/reminder accidental), use one of the following:
Delete an accidental directly by selecting it and pressing Del, note pitch corrects automatically.
To change the enharmonic spelling of a note, or notes, in both written and concert pitch views:
To change the enharmonic spelling in the written pitch view, without affecting the concert pitch view, or vice versa:
Note: If the pitches of selected notes are not all the same, the effect may be unpredictable.
