Accidentals
Accidentals are shown beside notes to indicate their pitch, both when notated on a staff and written out in text. In music based in Western tonality, they usually show that the pitch of a note has been altered so that it does not conform to the current prevailing key signature.
Accidental duration rules
Accidental duration rules determine how long accidentals apply, such as within a bar, at a different octave, or just for a single note.

Accidental duration rules

Accidental duration rules determine how long accidentals apply, such as within a bar, at a different octave, or just for a single note.

Dorico Pro allows you to use different accidental duration rules.

Common practice: In Dorico Pro, this is the default accidental duration rule. In common practice, an accidental applies for the duration of a bar and only to the pitch at which it is written, meaning each octave requires a separate accidental.
Second Viennese School: The Second Viennese School accidental duration rule requires writing every note with an accidental, including naturals.
Modernist: The Modernist accidental duration rule states that only notes that have been altered from the key signature show accidentals. Naturals are not shown.
