Music theory models in Go
There's an example command-line utility music-theory.go
to demo the libraries, with a bin/
wrapper.
To build and install music-theory

[Note](note/)
A Note is used to represent the relative duration and pitch of a sound.
[Key](key/)
The key of a piece is a group of pitches, or scale upon which a music composition is created in classical, Western art, and Western pop music.
[Chord](chord/)
In music theory, a chord is any harmonic set of three or more notes that is heard as if sounding simultaneously.
[Scale](scale/)
In music theory, a scale is any set of musical notes ordered by fundamental frequency or pitch.
