The flamenco Bulerías is the fastest branch of Soleares, with a lively, intense dissonance that compliments the advanced rhythmic structure of the compás. Bulerías are possibly the most popular, yet also the most virtuosic and demanding for flamenco guitarists. The typical Bulería ranges from 160-275 BPM (extremely fast). Bulería is usually played por medio, and includes chord variations of A, B flat, and C. Another important characteristic of the Bulería a rhythmic switch, where beat 12 becomes the strong downbeat and beginning of the compás.
