@PaperComposer Thank you!
Some words about flamenco. In this style, length phrases are not regular or uniform, surely because they follow the singer, whose lines are full of melisma, hyper-rubato, breaks, etc... Flamenco es very very complex.., if you go into the pulses of the time signatures you go crazy.... Well, it takes a life to master it.
On the other hand, I velive that although these pieces come straightly from dances, they take a new (cult) form when treated by academic composers.
