The seguiriya is one of the deepest and most serious forms in flamenco, and one of the oldest. Its compás has twelve counts like the soleá’s, but its accents fall so that the cycle is usually felt as five uneven beats rather than twelve even ones: two short, two long, and a short one to close. Its source prints it starting on 12, with the accents on 12, 2, 4, 7 and 10.
The accent no even count explains
Read against the two even ways of counting twelve, the seguiriya behaves differently from the soleá. Counted in twos, the cycle catches four of the five accents. Counted in threes, it catches only the first. And the accent on 7 falls on a downbeat of neither: it is only there because the two long beats in the middle of the cycle push it there. That single accent is the arithmetic behind the uneven feel, and it is why no amount of clapping in even groups will ever land on it.
The soleá’s cycle, started from 8
Its accents are not new ones. Start the soleá’s cycle on its count 8 instead of its count 12, and the five accents fall exactly where the seguiriya’s do; the shared-cycle line above works that out from the two declarations, and the source says the same thing in its own words. Sources also number the seguiriya differently: one counts it from 1, which puts every accent one count later than the numbering used here, while the accents themselves stay where they are. The page quotes both printings.
The cadence
The seguiriya is normally played in the flamenco mode on A — por medio, the home chord’s root on the open fifth string — so the page opens in A. The cadence is the four-chord fall its source prints for the flamenco key in that position, landing on the home chord. Its rhythm is often stretched and pulled by the singer, but the chords, like the cycle, stay put; pick another key and the same four are realised there.
