Rhythm

Feel the pulse under a looping conga marcha, which can't tell you which downbeat is which

Feel the downbeat under a looping 2-3 son clave

Feel the pulse under a campana bell, where a low tone marks the beat and a higher one fills in for color

Feel the pulse under a looping bass tumbao, with beat 4 landing loud as a decoy

Same son clave, opposite order: this time beat 1 has a hit instead of a silence

Feel the downbeat under a looping cáscara pattern

Feel the downbeat under a looping 2-3 rumba clave, son clave's cousin with a shifted third stroke

Same rumba clave, opposite order: this time beat 1 has a hit instead of a silence

Feel the pulse under a bongó martillo: a sharp slap on 1, 3, 5 and 7, an open tone on 4 and 8

Feel the pulse under a güiro's long-short-short caballito pattern

Feel the pulse under a shékere's sparse half-note shake

Hear a pattern and pick the instrument playing it.
