I read somewhere that depending on the civilization we live in, we are more inclined to see emotion in melody (pitches and harmony of the notes we play) or rhythm (when we play them) and that article said that if an Afro Cuban listened to Al di Meola, with his very percussive technique, he might just find it really beautiful, just like some western guys love Bach's praelude in C (no rhythm changes, just tension due to harmonic changes)...
