Product details
Balanced Proportions. Expansive Acoustic Expression.
The Yamaha B20 is the beautifully proportioned middle model of the new-generation B Series. At 116 cm high, it offers a meaningful step up in acoustic scale while remaining practical for living rooms, teaching studios and dedicated practice spaces. Its polished-ebony cabinet gives it a timeless presence without overwhelming the room.
A redesigned soundboard, newly developed B Series hammers and longer bass strings give the B20 a clear, open voice with satisfying warmth and dynamic range. Five back posts, a V-Pro frame and Yamaha’s tightly controlled manufacturing support the stability, touch consistency and longevity expected from a serious acoustic piano.
Signature Features
A Versatile 116 cm Upright
The B20 balances compact placement with a larger soundboard area than the B10, giving pianists broader dynamic range and a richer, more expansive acoustic response.
New-Generation B Series Hammers
Specially developed hammer felt draws on knowledge gained through Yamaha’s CFX concert-grand development, producing a focused, resonant voice that keeps melodic lines clear across the keyboard.
Redesigned Soundboard
The new soundboard is engineered for clear, spacious resonance. Its carefully formed crown converts string energy efficiently and helps the compact cabinet breathe with a natural acoustic response.
Longer Bass Strings
An optimised bass-string scale supports stronger pitch stability and a richer low-register foundation, creating a more balanced transition from bass to treble.
Five-Post Structural Support
Five back posts reinforce the cabinet and help preserve the soundboard crown against string tension, supporting long-term stability and consistent resonance.
Precision Yamaha Action
Accurately machined action components are carefully assembled for a smooth, predictable touch that supports developing technique, dynamic control and confident repetition.
Full-Length Music Stand
The redesigned wide stand runs across the fallboard, providing generous support for multiple scores, large books or unfolding music, with a deep non-slip surface for added stability.
Soft-Close Fallboard
A built-in soft-close mechanism allows the key cover to descend gently, adding convenience and reassurance in busy homes, studios and teaching environments.
