So far I've done Solea (a lot), tangos, zapeteado, and seville. I like Bulerias a lot, that's probably like the Be-Bop of Flamenco, very challenging. Sevilles' a lot of fun, it's kinda of up-beat and festive, it's basically flamenco dance music. The count is in 6. It's usually just 2 chords (lets say E7 and A), the E7 would be played on counts 1 & 2, the A on counts 3,4,5,& 6...w/a rasguedo on the up-beat of 4. So it would be (E7) 1 + 2 + (A) 3 + 4 E&A 5 + 6 +.
It's kinda good to get really good at Solea 1st, since thats the basic rhythm for other song forms like Bulerias, Seguiriyas, Fandango, and Alegrias.
Which Juan martin book do you have? Is it the one published by Mel-bay that comes with a cd & dvd?
