The strumming technique is called rasgeudo (sg pronounced like H in spanish). There are many different methods of doing this, the most common being pinky, 3rd, 2nd, 1st, followed by an up-stroke w/the 1st. This pattern would occur during 1 beat, the P321 being 32 notes, and the up stroke being an 1/8th note. Having fingernails will help you.

Single notes are played using the fingers...very simuliar to classical style but with a bit more finger nail attack and the hand held more in a curved fashion.

The songs are based off of specific forms (Solea, Bulerias, Sevilla, rhumba, etc.) that specify where the accents will fall.
