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, you can also design your own custom accidentals and combine them into custom key signatures as appropriate for your project.

You can find existing tonality systems in your project in the Tonality System section of the Key Signatures, Tuning Systems, and Accidentals panel. You can open this panel by clicking Key Signatures, Tuning Systems, and Accidentals in the Notations toolbox in Write mode.

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

  • New Tuning System

    Allows you to create a new tonality system.

  • Edit Tuning System
