Tangos — the flamenco palo in a binary compás: four beats, counted in eight across two bars of 4/4, not the twelve of soleá or bulerías. It is festive and earthy, the family that tientos (slow) and rumba (pop) grew out of. Written here por medio, in A Phrygian: the guitar vamps on A with the half-step Bb above it, the flamenco cadence that makes A sound like home without a key signature saying so.
How it sits: the palmas are silent on 1 and clap 2, 3 and 4 — the hole on the downbeat is the style's signature. The guitar lets the 1 ring, plays a muted golpe (x) on 2 and 4 and accents 3. The cajón gives the bass tone on 1 and 3 and the slap on 2 and 4, with light ghost strokes between.
Listen for the guitar filling the gap the palmas leave on 1, and the A–Bb–A swing across the eight counts.
Practice: clap 2-3-4 with the palmas, saying "one" silently, until the empty beat feels like the strong one.
