Chordal Framework
By restricting the choice of melody to fit the harmony of the associated category, it is hoped that the combination of appropriate objects and actions will sound 'correct' in accordance with the harmonic grammar, whilst inappropriate pairings will result in combined melodies and chords which sound 'incorrect'.

To reinforce the harmonic structure, the underlying chords can be sounded together with the grammatical melodies. As the melodies are based upon their underlying chords they will not clash.

Furthermore, the audio representation of any combination of actions and objects will maintain its grammaticalness regardless of whether melodies and chords or melodies alone are sounded.
