Tonality systems

The term “tonality system” is used in Dorico Elements 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, or EDO. For example, standard Western scales with half-step (semitone) steps have 12-EDO.

  • A set of accidentals. This allows you to notate how much a note is raised or lowered.

  • A key signature. In Dorico Elements, you can use any traditional Western key signature.

In Dorico Elements, you cannot change the tonality system; this is only available in Dorico Pro.
