TransAcoustic™ Piano

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

TransAcoustic™ pianos are equipped with Bluetooth® MIDI. Download the Smart Pianist app on your smart device and connect wirelessly to your TransAcoustic™ Piano to enjoy simple, intuitive control of your instrument's features. *Unavailable in some areas.

Making Sounds Resonate

Pressing a key on an acoustic piano causes its hammer to strike the corresponding strings, making those strings vibrate. The initial sound is small, but it's amplified by the soundboard with the entire body of the piano serving as a resonator. The result: the distinctively rich sound of an acoustic piano. TransAcoustic™ technology employs this same mechanism of resonance keyed by the soundboard through a digital tone generator.

Creating Acoustic Sound From Digital Audio Sources

With TransAcoustic™ technology, there's no need for a speaker unit, even though the sounds are generated digitally. All that's required is a transducer. In TransAcoustic™ Mode, the hammers are stopped immediately before striking the strings, and sensors installed below the keys decipher how they are played. The transducer's job is to convert the digital signals that represent your input into vibrations, and then relay them to the soundboard. The soundboard amplifies the vibrations, and the entire piano vibrates sympathetically. Even though the sound is digital, it goes through the same mechanism of resonance, meaning that the sound that reaches your ears is as rich as that of an acoustic piano. You can also control the volume and still enjoy the feel of playing an acoustic piano.

A Special Transducer for Acoustic Pianos

Conventional transducers are too heavy to install on a piano soundboard; their weight compromises its essential functions. To address this problem, Yamaha developed a transducer exclusively for acoustic pianos. Yamaha's transducer faithfully reproduces the natural sound of acoustic pianos without inhibiting the functions of the soundboards.
