Terceto Nano was a Cuban trova trio founded by singer/songwriter Román León, nicknamed "Nano", and active during the 1910s. It is noted for being one of the earliest groups in the transition from the traditional vocal duet with guitar accompaniment to the vocal trio with one or two guitars. Between 1911 and 1916, the trio recorded 24 songs in Havana for Victor. Such recordings are among the first made a Cuban terceto, and among the first recordings of punto guajiro made by actual trovadores.
