Son-urbano - genre

When son migrated to Havana (1920s–30s), it became more polished and arranged for city audiences. Instruments:

  • All from Son-tradicional, plus:
  • Double Bass (instead of marímbula, more volume and projection)
  • Trumpet(s) (added for melodic/solo lines)
  • Piano (sometimes, for harmonic richness in bigger groups)
  • Congas (occasionally added, blending with bongó rhythms)
  • The septeto format (with trumpet) became the standard.

Sextetos in Havana (1920s)

When son first hit Havana, the sexteto format (6 instruments, no brass) was the model: guitar, tres, bongó, claves, maracas, and bass. These groups were lighter, closer to the rural sound but polished for urban dance halls. Famous example: Sexteto Habanero.

The Septeto Innovation (late 1920s–1930s)

Adding a trumpet turned the sexteto into a septeto, giving it more projection for bigger venues and open-air dances. The trumpet also added space for improvisation, call-and-response with the singer, and a more “urban” flavor. Example: Septeto Nacional (Ignacio Piñeiro).
