Simply Play Your Acoustic Piano

At its heart, the TransAcoustic™ Piano is a genuine acoustic instrument. For more than a century, Yamaha has crafted pianos that inspire players to develop and express themselves, mirroring their thoughts and feelings with rich sound and reliable quality.

Control the Volume as You Play

Turn on TransAcoustic™ Mode so that you can use the volume control to continue playing without disturbing others. Although the sound is now being created digitally, the soundboard still vibrates and the strings and the body of the still resonate, so that you hear the music as well as feeling it through your body.

Use Your Piano as a Speaker

Enjoy listening to preset songs, recordings of your own performances and even music from your smartphone or other devices via Bluetooth®.* You can also play along with songs streamed from your devices, adding the piano part for ensemble performances. *Unavailable in some areas.
