Whether you're practicing at home or away, performing solo or in a band, the Yamaha P-155 digital piano offers professional quality sound with our legendary piano touch. Thanks to the top-shelf Yamaha digital piano technologies like advanced sampling methods and the ultra-expressive GH (Graded Hammer) keyboard, musicians don't have to choose between portability and piano qualitythe quality you expect from a company that's been building world-class acoustic pianos for over a century. In the P-155, Yamaha crafts that heritage into a slim cabinet available in three contemporary finishes.
Dynamic Expression, Realistic Sound
Hand-crafted Pianos, High-quality Voices

To ensure the finest grand piano sound for the P-155, we went straight to the source: Yamaha's finest 9-foot concert grand, a hand-picked CFIIIS. Next, a master piano technician painstakingly tuned and regulated the CFIIIS to sonic perfection. Then we applied our Pure CF Sampling technology to accurately capture every aspect of the CFIIIS sound, keeping post-processing to an absolute minimum to maintain sonic integrity throughout. The result is a truly authentic grand piano sound with powerful, dynamic bass, warm mid-range and crystal-clear highs.

Layer upon Layer
Using Yamaha's Dynamic Stereo Sampling (DSS) technology, the incredibly natural 4-level piano sample is a breakthrough achievement for digital pianos. It means that, depending on how hard you strike a note, you will hear one of four piano recordings on each and every key for an unprecedented level of dynamic range and tonal expression. Playing softly doesn't simply lower the volume; it produces the quiet recordings of piano notes. And likewise, playing more forcefully triggers separate samples at different levels.

Attention to Detail
If you close your eyes while playing a grand piano, you'll find its sound is a bit more complicated than "note-on-noteoff." Yamaha has gone to great lengths to capture these sonic artifacts in the P-155. These meticulous efforts include recording a felt damper coming to rest on a vibrating string when a note is released [Key Off Samples], or reproducing the sound of the open strings that wash over your performance when using the damper pedal [Stereo Sustain Samples and Damper Resonance].

A Touch Above
Look inside the lid of a grand piano. Different sized strings require different sized hammers. Different sized hammers have different weights. The keyboard of the P-155 utilizes Yamaha's GH (Graded Hammer) technology to reproduce the true "feel" of a grand piano keyboard action, with heavier touch in the lower keys, lighter touch in the higher keys, and subtle gradations of weight and response throughout. Thanks to the input of concert-level, professional pianists during its development, the GH keyboard features superb balance and remarkable consistency. Performing or practicing on a GH keyboard properly develops and maintains an artist's technique for making the transition between P-155 and an acoustic grand.

Perfection Made Practical
As a full-featured digital piano, the P-155 gives you all you need for practice, playing and performance. It has an internal high-power, two-channel (12W + 12W) amplifier with high-performance speakers built-in-letting you and your audience hear the authentic sounds in their full glory.
