Yamaha B20 SC3 Silent upright pianoYamaha B20 SILENT Piano: Performance when you want it, silence when you need it The second model in the new 2026 Yamaha B series, the B20 measures 116cm tall and is the first model in the range to feature traditional style cabinetry with a front pedestal leg and castors. Its size means longer strings and a larger soundboard than in the smaller B10, which along with upgraded under felted hammers translates into a much more powerful and resonant tone.
