## 2.9 Ancient notation

Support for ancient notation includes features for mensural notation, Gregorian chant notation, and Kievan square notation. These features can be accessed either by modifying style properties of graphical objects such as note heads and rests, or by using one of the pre-defined contexts for these styles.

Many graphical objects, such as note heads and flags, accidentals, time signatures, and rests, provide a `style` property, which can be changed to emulate several different styles of ancient notation. See

- Mensural note heads,
- Mensural accidentals and key signatures,
- Mensural rests,
- Mensural clefs,
- Gregorian clefs,
- Mensural flags,
- Mensural time signatures.

Some notational concepts are introduced specifically for ancient notation,

- Custodes,
- Divisiones,
- Ligatures.
