Autumn Leaves (CBR only)

In this example, no PACT is activated. The fragments are retrieved only based on the similarity between the current context (e.g., underlying chords, position within the song, previous chords, previously played fragment, etc.) and the original context of the case base fragments. This line is much more rich and interesting the than the previous one. However, it lacks coherence and homogeneity: there is no big difference between the first (theme exposition) and second (improvisation) chorus; some too dissonant or too dense phrases (as those of measures 1, 5-7, 9, 16, etc.) should be avoided at the first chorus, and so on. The expert who worked with us considered that playing a B on a Cm7 at the first measure was not a "logical" choice.
