Septeto Nacional (National Septet), or the Septeto Nacional de Ignacio Piñeiro, is a Cuban group credited with expanding the Son musical style before Arsenio Rodríguez.
In the same year, Lázaro Herrera took over the group when Ignacio Piñeiro left it for financial reasons - despite their success the musicians earned very little.
The group disbanded in 1937 but resumed playing for a recording session in 1940 and a television appearance in 1954.
Its CD Poetas del Son was nominated for a grammy in 2004.
