Step Up to Premium Yamaha Touch & Tone

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 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.

"Ascension" 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.

5.0 out of 5 stars Best in class digital piano if you are concerned about learning to play correctly October 21, 2010

By Joel Avrunin TOP 500 REVIEWERVINE™ VOICE

Color Name:Mahogany

I recently did an exhaustive review of the digital piano world as I am trying to teach my children to play the piano. Accoustic pianos are not a choice due to the size, weight, cost, and tuning requirements. I love the idea of a piano that is always in tune (and can move if we move), but I wanted to be sure I was teaching my kids in a way that they could easily play a grand piano if presented with one. The biggest concern is muscle memory, and making sure their fingers are used to the feel of a real key.

Roland makes some of the top-of-the-line pianos, but they also come with a high cost. I am sure the sound might be a bit better, but I could not justify the expense. I tried out some of the higher-end Yamaha pianos, and while I was impressed, still was shocked at the cost. The P85 was the lowest cost Yamaha piano I tried that seemed it could be good for teaching. It sounded nice, feature the weighted keys with "graded hammer standard" (GHS), and was reasonably portable. However, I felt the P85 keys were a little hard to push with a little too much return. I had a higher-end Yamaha nearby (non-portable) and found the keys much better. The store also had a grand piano, and the higher-end Yamaha was much closer than the P85.

With a little research, I discovered that the high-end Yamaha pianos (the ones that cost $2k and up) use "graded hammer effect" (GHE), a step up from GHS. Since the discontinuation of the P-140, the P-155 is the least expensive piano to support GHE. It also has 128 note polyphony, 14 voices with 4 tonal varieties, and support for a sustain pedal (you only need 1 pedal for most playing).

What are the downsides to the P-155? Some other digital pianos have far more voices, more recording capability, and louder speakers. The P-140 only had 6-watt speakers. This was improved with the P-155 (12W speakers), but it is still not the best.

For the class of piano that this is, the improvements do not justify the price upgrade from the P-140 to the P-155, but if you are just starting out, there's no better piano for the price. And if you can get a good used deal on a P-140, it will be just as good.

5.0 out of 5 stars Top notch portable piano. November 14, 2009

By SOu

Color Name:Mahogany

After a year owning the Yamaha YPG 235 (still love it), I decided to move up to something more substantial, with weighted keys. My first gut reaction was a Kawai or Yamaha Clarinova, but the cost was a bit high, and I didn't like the fact that it was not portable. I wanted the features without the cost (typical consumer). So I looked at the P155.
This keyboard comes with 4-level AWS sampling, 128 polyphonic and GH effect (Yamaha's best) weighted hammers. The features are in line with mid-level Clarinovas. Yamaha did a great job reproducing there top of the line grand piano, trouncing the YPG-235 and the YPG-635. There are subtle sound effects from a real piano reproduced, making the whole experience very realistic.
The keys are extremely accurate, but somewhat heavy. The change over from the graded-tough YPG 235 to a super weighted keyboard took about 5 days. The advantage is being able to play on a real piano without the fatigue, now that the muscle in my hands have bulked up.
This machine has real MIDI ports, 12 Watt speakers, 1/4" plug connectors for an amp, and up to (2) headphones. It has a USB port for storing songs onto ONLY. You cannot use this port for anything but storage (like a USB pen drive). The unit will format your "drive" to Windows FAT, but it is writable-readable on MAC/LInux . You will need a MIDI to USB adapter if you want to play on your computer.
Overall, I feel (as a novice still) that I took the right course, buying the YPG-235 and now the P-155. The P-155 is truly a mid-level professional stage piano, at a very fair price. The quantity of samples (instruments) is not as much as the YPG-235, but the trade-off is a really superior instrument.

Made in Japan. (Ok, Made in USA would be better....but it's a Japanese piano company)

4.0 out of 5 stars Great Practice Piano, Nice Sound, Good Features February 9, 2010

By D. Bolas

Color Name:Ebony|Amazon Verified Purchase

Dont expect a big difference in sound quality over the P-140 or you will be dissapointed. At most there may be an ever so slight increase in micro-dynamic expressiveness on softer, subtle passages (maybe that's the 4th layer?), but dont expect anything to jump out at you. I mean subtle! Not much difference in the decay versus the P-140. About the same. I owned them both. The action is heavy and responsive on the P-155 (same as P-140) which I like and the features are an improvement over the P-140. Given how inexpensive and small digital memory has become, it would be nice if Yamaha could give us a DP with a natural sounding decay instead of a looped one. On a real piano the harmonic overtones decay faster than lower fundementals. This sonic reality has not been incorporated into this instrument unfortunately. The P-155 does sound resampled, just not enough to show a really audible difference from the P-140. At soft levels its pretty good but at mezzo forte or louder decay is unnatural, like the P-140. Sound quality via the built-in speakers is the same as P-140. Dynamic range and volume is a little better because of greater wattage but thats about it. Speakers and frequency range are unchanged. Unlike P-140 you can choose brightness levels in between Bright, Normal and Mellow for a total of 5, not 3 choices which is nice. If you can get one for $1,000 or less its worth it but I wouldn't spend 1200 on it over the P-140, unless you need the new features.
