App Description

SET-CLASS FINDER is useful for:
- Students studying atonal or post-tonal music
- Composers, theorists, musicologists
- Teachers of music theory or composition

Set-Class Finder is a flexible tool that calculates any musical set from 0 to 12 different pitch classes, providing the following properties of the input set:

- Normal Form (Normal Order)
- Forte name with TnI transformation information
- Interval-Class Vector
- Prime form (both Forte and Morris/Rahn versions)
- Z-correspondent
- M/MI-related set-class
- buttons to flip set to its complement and inversion, showing all of the above information.

The set can be entered by typing it in (using 0-9, t/e or A/B for ten/eleven), or can be entered by tapping on the appropriate pitch-classes in the circle.
