Yamaha B20 TC3 TransAcoustic upright piano

Yamaha B20 TransAcoustic™ piano: Expanded sound with complete control

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.

First and foremost an acoustic piano, a TransAcoustic piano is a versatile tool which combines the best features of a digital piano with the inimitable resonance and feel of an acoustic instrument. Specially positioned transducers transform the piano's soundboard into a natural loudspeaker, meaning you can practice at a lower volume without wearing headphones. TC3 includes useful features such as a built-in record facility, a metronome, 20 rhythm accompaniments and compatibility with apps including Smart Pianist.

An excellent choice of mid-size upright for the family home or practice space, the B20 TC3 TransAcoustic is an extremely capable piano and ideally suited to the intermediate player.

Clear, balanced acoustic tone that develops over time

The B20 has been designed to produce a pure, clearly articulated tone with a natural sense of resonance. Its scale and soundboard design ensure balance across the keyboard, with a warm bass supporting a clear and focused treble.

As the piano is played over time, the natural materials used in its construction begin to mature, allowing the tonal character to develop further. This gradual change gives the instrument a more familiar and expressive voice, supporting long-term enjoyment.

TransAcoustic™ technology for natural volume control

Sound continues to resonate through the soundboard even at reduced volume levels, preserving acoustic character.

Bluetooth functionality allows for playback and interactive practice.

Refined hammer design for clarity, control and sustain

The hammers are processed using a method derived from Yamaha’s flagship CFX concert grand piano. By preserving the natural elasticity of the felt, this approach allows each note to sound clearly while maintaining consistent sustain.

This results in a tone that remains stable across all registers, helping both melody and accompaniment to come through with clarity as players develop their technique.

Redesigned soundboard and improved resonance

The larger cabinet allows for a bigger soundboard and longer bass strings, delivering greater tonal depth and a wider dynamic range.

The solid spruce soundboard and five back posts ensure consistent resonance and long-term stability.

Precision action for consistent performance

The action mechanism consists of over 60 precision components per key, manufactured to extremely fine tolerances. This ensures smooth operation and a responsive touch, allowing players to control dynamics accurately.

Consistent performance across the keyboard supports both early development and more advanced playing over time.

Built for lasting quality and stability

Wood selection and drying are carefully controlled to ensure long-term stability. Yamaha’s seasoning process stabilises moisture content, helping to prevent warping while maintaining tonal consistency.

The frame is designed to withstand over twenty tons of string tension, supporting both structural integrity and acoustic performance, while precision-manufactured tuning pins contribute to reliable tuning stability.

Designed for practical, everyday use

A wide music stand extends across the fallboard, providing stable support for larger scores and improving playing space. Its non-slip surface helps keep sheet music securely in place.

The soft-close fallboard mechanism allows the lid to close gently and safely, protecting hands while maintaining a clean, refined appearance.
