- would it be possible to segment chord in a song in a fuzzy way?
- ie. the segments needn't be disjoint

- would it be possible to perform multi-level (hierarchical) segmentation?
- on one level there would be a longer block with a simple chord
- one another level this block would be composed of smaller block with more complex chord - interaction of basic chords and melody
- how to discriminate between chords and melody?
- sometimes melody is quite independent on the underlying chords
- sometimes chords are made of melody
