Son-urbano

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.
