Jazz samba — bossa nova as American jazz players took it up in 1962 (Jazz Samba, Getz/Byrd, then Getz/Gilberto): a little faster and harder than João Gilberto's guitar, with a jazz drummer's kit. The drums play straight eighths on the hi-hat (brushes or sticks), a samba bass drum (1, and-of-2, 3, and-of-4), and a cross-stick on the bossa clave — that is the clave layer here, 3-2.
The bass plays in two — root and fifth, half notes — and the piano comps with rootless two-hand voicings that anticipate the next chord on the and of 4, then answer the clave's 2-side (beat 2, and of 3) in the following bar.
Listen for the anticipation at the end of bars 1 and 3: the new chord arrives half a beat early and the downbeat is left to the bass. Practice: mute the piano and clap the clave against the bass, then play only the anticipations. The changes are the opening of "Desafinado", in F.
