What is SILENT Piano™?


When the SILENT Piano™ function is activated, the hammers will no longer hit the strings and instead, a highly sophisticated sensor-technology captures all movements of the keys and sends them to the digital tone module. Play a real acoustic piano with headphones at any time, day or night without being disturbed or disturbing others. The Yamaha Silencing System is unsurpassed, allowing 24hr practice as well as possessing many other features including a range of pre-installed sounds, being able to record your own performances or connecting mobile devices to use the latest Apps.


Two World-Renowned Piano Sounds


You can play SILENT Piano™ SC3 type with the voices of CFX, Yamaha’s finest concert grand piano, and Bösendorfer’s legendary Imperial. All 88 keys are sampled individually. As Yamaha’s flagship grand piano, the majestic CFX boasts a wide palette of tonal colors, from sparkling high notes to powerful bass tones. The legendary Bösendorfer, meanwhile, is renowned for its sonorous and rich Viennese sound.


10 Various Voices


SILENT Piano™ SC3 type offers total 10 pre-installed sounds such as electric pianos, harpsichord, organs, strings, choir, and synth pad, allowing you to select the ideal voice to match your preferred musical genre.
