Seguiriya (siguiriya) — the darkest of the flamenco palos, a cante jondo of grief. Its twelve counts are grouped 2+2+3+3+2, written here as an additive bar so the grouping is in the time signature: five uneven beats, short-short-long-long-short, not twelve even pulses. It is the soleá compás started from a different count (soleá's 8), which is why it sounds like the same wheel turning from the wrong spoke. Key: A Phrygian (por medio), A to Bb and back.
How it sits: palmas clap only the five beats, louder on the two long ones. The guitar strikes an accented rasgueo on each beat, with an upstroke (and a muted stroke in the long beats) filling the eighths. The cajón — a modern addition; traditional seguiriya is voice and guitar — gives bass tones on beats 1 and 3 and slaps on 4 and 5.
Listen for the two long beats in the middle: they are where the singer stretches.
Practice: count 1-2, 1-2, 1-2-3, 1-2-3, 1-2 and clap each 1.
