Play Solo: Plays just the melody line.
Play Original: Plays the melody with the original (human) harmonisation.
Play A.I.: Plays the melody with an A.I. generated harmonisation.
Play Worse A.I.: Plays an A.I. generated harmonisation, but one which the computer judges to be worse than its' best. This illustrates that the computer can create multiple harmonisations, and then judge which are good and which are bad. That is, it has learnt a form of musical taste.
