Rumba clave

The son clave with the third hit pushed back one sixteenth (an eighth in a 4/4 chart), from beat 3 to the and-of-3. That one displacement makes the pattern restless: the 3 side no longer resolves on a beat. It belongs to guaguancó and the other rumbas, to 6/8-derived music, and to the harder-edged salsa and timba styles. Notated here as one bar of cut time; in a 4/4 chart it spans two bars. Hear it against the son clave and notice the "late" third note.
