Isaac Oviedo picked up the tres as a boy in rural Matanzas and by his twenties had turned it into something closer to a one-man rhythm section, pioneering the thumb-driven alzapúa stroke that let him voice bass, melody, and syncopated fill all in the same pass. As founder of the Sexteto — later Septeto — Matancero, he carried that vocabulary onto record for RCA Victor in the late 1920s, laying technical groundwork that a generation of city-bound treseros, Arsenio Rodríguez among them, absorbed by ear.
