TransAcoustic™ pianos are genuine acoustic pianos, equipped with a volume control feature powered by Yamaha’s latest technology. While it’s also possible to play silently through headphones, the TransAcoustic™ Mode allows you to control the volume of your piano, so you can play without disturbing others. Even at low volumes, the soundboard vibrates so you can enjoy the full, physical sensation of natural acoustic sound as you play.

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



TransAcoustic™ pianos make it possible to play with true acoustic sound under normal circumstances, or to turn on TransAcoustic™ Mode so that you can use the volume control to continue playing without disturbing others. In TransAcoustic™ Mode, your piano becomes a speaker, so you don’t have to wear headphones or deal with bothersome and unsightly cables. 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. With near-acoustic resonance in TransAcoustic™ Mode, you can continue to make progress in your daily practice without disturbing family members or neighbors.

Play silently with headphones



TransAcoustic™ pianos are also equipped with SILENT Mode, so you can plug in headphones and enjoy realistic piano sounds at any time of the day and night, without disturbing anyone—or anyone disturbing you.

Use your piano as a speaker!



You can use your TransAcoustic™ Piano as a speaker and 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. Both the external music and the sound of the piano pass through the soundboard and body of the piano, combining to create a rich resonance. *Unavailable in some areas.
