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 quality—the 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.

Pure CF Sampling for superb tonality

Yamaha technicians selected a CFIIIS full concert grand with the highest sound quality, and tuned it to the finest possible condition. They then used our unique Pure CF Sampling technique to sample all of its sounds, in order to create the sound on this instrument. As a result, you enjoy the same natural tonal response as a top-quality piano.

4-level Advanced Wave Memory (AWM) Dynamic Stereo Sampling

The AWM (Advanced Wave Memory) is a sampling system which creates sound close to that of an acoustic instrument by using digital technology to record the instrument sound and applying high-quality digital filter technology to the recorded audio samples. The waveform of the sound created by playing the key of an acoustic piano differs depending on the playing strength from pianissimo to fortissimo. The AWM Dynamic Stereo Sampling analyzes these samples can produce such dynamic nuances by recording samples of various playing strengths. The greater the number of samples used, the higher the expressive quality and potential becomes.

Key-Off samples, Stereo Sustain samples and Damper Resonance

If you close your eyes while playing a grand piano, you'll find its sound is a bit more complicated than "note-on-note-off." 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).

128-note polyphony (max.)

Conventional digital pianos quickly run out of notes during fast, dense legato passages: sustained notes are cut off as the instrument "steals" notes to make room for new notes. A maximum of up to 128-note can be played at once.

Graded Hammer (GH) keyboard

Just as on an actual grand piano, the lower keys are heavy in touch and the higher keys are light, with all the natural gradations in between.

USB Direct Play

Simply connect a USB flash memory device to the instrument, and your favorite songs in MIDI format are ready to be played in random or sequence.


Insert a USB flash memory in the USB TO DEVICE terminal on the instrument. It would let you save or load the registered settings and user songs created on the instrument, as well as read data from the connected device.

Built-in Stereo Speaker System

This instrument uses highly efficient amplifiers that pack more sound into a lighter digital piano. With 12 watts per channel, these keyboards are ready to go whenever you are.

50 Preset Piano Songs

A selection of 50 different piano songs is provided for your listening pleasure. These recordings were chosen for their beauty as well as their functionality. Since many of the songs are classic piano pieces, anyone taking lessons can listen to them for reference.
