Samba-funk (and its jazzier cousin samba-jazz) is the drum-kit samba of 1960s–70s Rio studio bands, Azymuth and the samba-rock scene: the bateria collapsed onto one drummer and sat under electric bass and Rhodes. Written in cut time like the other sambas (half = 95).
The kick plays the surdo: beat 1, the last sixteenth of beat 1, beat 2 (the heavy one), and the last sixteenth again, a dotted "boom ... ba-BOOM" that never stops. The hi-hat runs straight sixteenths (the eighths here) like a chocalho, and the cross-stick spreads a two-bar tamborim-like figure over the top. The bass doubles the kick, root on 1 and fifth on 2, each approached by its pickup, and the Rhodes comps off the beat in the gaps between cross-stick hits.
Listen for the kick and bass locking into one instrument.
Practice hint: play kick and hat alone at half tempo before adding the cross-stick.
