Tonality systems

The term tonality system is used in Dorico to encompass three crucial elements that together make up the concept of tonality.

The three elements that make up tonality systems are:

• A number of equal divisions of the octave. For example, standard Western scales with semitone steps have 12-EDO.

• A set of accidentals. This allows you to notate how a note is raised or lowered. This can be a traditional set of accidentals, a set selected from the wide variety available, or a custom set of accidentals of your own design.

• A key signature. This can be a traditional Western key signature, or a custom key signature of your own design.
