Bulerías is one of the hardest flamenco rhythms to get a grip for dancers at any level. It can take a while before you can hear the accents in the guitar and from there figure out how to get in and out of bulerías in compás.
For the basic shape of bulerías the accents are on beats 12, 3, 6, 8 and 10.
12 1 2 3 4 5 6 7 8 9 10 11 12...
In this video Manuel 'El Marmol' is playing basic bulerías compás on the guitar. Watch the video and see if you can hear where the accents are. If you need a hint to get started you can watch Manuel's foot tapping out the accents or listen for the golpes (finger taps) on the front of the guitar.
