Custom tonality systems

Custom tonality systems allow you to specify a unique number of divisions of the octave for your project. This can be useful for music not based on traditional Western harmony. In Dorico Pro, you can design your own custom accidentals and combine them into custom key signatures within each custom tonality.

You can find existing tonality systems in your project in the Tonality System section of the Key Signatures, Tonality Systems, and Accidentals panel.

Dorico Pro provides two tonality systems in each project by default: Equal temperament (12-EDO) and Equal temperament (24-EDO).

You can create custom tonality systems and edit existing tonality systems in the Edit Tonality System dialog. You can also export tonality systems, for example, to share them with other users. Tonality systems are saved as .doricolib files.
