A tool to easily explore music theory principles.
Usage: kord.exe [COMMAND]
Commands:
describe Describes a chord
play Describes and plays a chord
loop Loops on a set of chord changes, while simultaneously outputting the descriptions
guess Attempt to guess the chord from a set of notes (ordered by simplicity)
listen Records audio from the microphone, and guesses pitches / chords
help Print this message or the help of the given subcommand(s)
Options:
-h, --help Print help information
-V, --version Print version information$ kord describe Cmaj7
