It is difficult to imagine composing music based on a single scale and a single chord. But this approach has the advantage of leaving the computer the possibility of transforming elementary music into complex musical structures.
In this video we see a particular process of transformation. A solo from a jazz standard has been analyzed and converted to an extremely simple harminic structure, based on a chord (C major) and a scale (C major).
One can then edit the transformed solo without paying attention to the harmonic structure. For example we can invert the measures, or remove the parts we don’t like. From the solo edited in C, we can then transform it to any harmonic structure (chords and scales).
