About

Start playing notes using your connected MIDI device or computer keyboard. If you play a triad or a seventh chord, in either root or inverted position, it will be identified and relevant scales shown. Chords in open position and/or with doubled notes will also be identified where possible. Note that not every chord and scale is supported at this time.
