Explanation

A musicOnVisual access mode indicates that a publication contains images of musical scores. It is expressed in metadata using the musicOnVisual value.

As musicOnVisual describes a characteristic of visual content, it is considered a modifier of the visual access mode value and you should always pair the two values together.

The value is also commonly paired with textOnVisual if, for example, the lyrics for a musical score also drawn in the image canvas.

It is also possible to pair musicOnVisual with colorDependent if color perception is the only way to differentiate information (e.g., color coding to help learners read music).

As support for rendering markup languages that represent musical scores is not generally available, using images for music compositions is common. Consequently, a musicOnVisual access mode would be typical for any publications produced using the EPUB format that contains music scores. It is only relevant to an audiobook if it also contains supplementary material beyond the audio.
