This system helps a musicologist explore innovative harmonic idioms. The user chooses harmonic idioms that the system then blends (e.g. by creating transitions between cords). The system presents its harmonic blends to the user, who can evaluate and influence the next set of generated blends.
‘This tool allows a music expert to specify arguments over given transition properties. These arguments are then considered by the system when defining combinations of features in an idiom blending process. A music expert can assess whether the new harmonic idiom makes musicological sense and re-adjust the arguments (selection of features) to explore alternative blends that can potentially produce better harmonic spaces.’
