Revision: Yamaha YPG-635 88-key portable grand piano

Combining exceptional piano sound with an attractive wood finish and adding a number of useful and advanced features, the Yamaha YPG-635, an 88-key portable grand piano, could be the ideal portable digital piano for you. After this review, you'll know much more about the YPG-635, including its advantages and disadvantages and other important considerations. So let's start with a review of Yamaha's leading consumer digital piano...

The Yamaha YPG-635 is equipped with standard 64-note polyphony, a two-way speaker system (separate woofers and tweeters), a convenient digital display, a multi-track recorder, built-in reverb effects, and digital signal processing (DSP) that adds various special effects.

In addition, Yamaha also features a fully adjustable metronome, ideal for anyone taking piano lessons. You also get a total of 130 voices, 12 special effects and drum kits, and 361 XGlite voices, an impressive list of voices and features for such an inexpensive piano.

Yamaha YPG-635: the good stuff

For me, the big selling point of the Yamaha YPG-635 is the action of the piano; it's very similar to a real piano. Just like a real acoustic piano, the standard heavy hammer action keys provide a response and feel that seems heavier in the lower parts and lighter in the upper notes. Every time I play this model, when I see it on display in a music store, I am always surprised at how much fun it is to play.

Equally impressive is the pleasant sound quality of the grand piano, made possible by Yamaha's advanced wave memory technology, which produces exquisitely realistic sounds. What makes the sound quality even better is the digital signal processing that enhances the overall sound quality of the piano and takes it to the next level.

I can't let this test pass without mentioning the appeal of this model. The neutral wood accents make it one of the most attractive portable pianos I have seen in a long time and make it the perfect complement to any room.

Yamaha YPG-635: The wrong one

I have sometimes been overwhelmed by the number of features of the YPG635. As someone who only likes to sit and play the piano, it can be overwhelming. However, once you've read the manual and discovered the function of each button, you won't have any more problems. Note: For those who just want to play the piano, they can press the "Portable Grain" button as shown below in the picture.

Another possible disadvantage of this model would be its small screen which can be a big obstacle for those who depend on the screen for digital scores while they play. Unfortunately, there is no option available to enlarge it.

The volume of the speakers could become a disappointment for those who want or need to play with the YPG-635 in front of a live audience. Most of the time, it may be necessary to set the keyboard volume to maximum, unless external amplifiers can be used.

This digital piano is perfect for :

  • Start studying piano as you can:
    • Playing digital scores on the screen
    • record your workouts
    • use the built-in metronome
  • accomplished musicians who want the sound and feel of an acoustic piano without paying a high price.
  • a person with little space in their house or apartment, because this attractive portable piano can fit almost anywhere.

The final verdict

Overall, the 88-key Yamaha YPG-635 portable grand piano is an excellent purchase given its realistic grand piano sound and authentic piano action. It is less expensive than the latest Yamaha DGX-630, which is essentially the same piano.

In short, when you consider the many features that Yamaha has incorporated into this piano, nothing comes close. In a way, Yamaha has found the perfect spot for sound, action, features and price. This is a remarkable achievement in a very competitive market.

This model scores so incredibly well on all criteria that I have no hesitation in giving Yamaha's flagship, the YPG-635, the highest marks of all. So when it comes to finding a great portable digital piano at a reasonable cost, this particular model should be the first on your list to consider.


A review of the owner of the YPG-625

By B. Renton

Wow! I couldn't be happier with this keyboard. It looks like a real piano, not to mention the other 500 sounds you can get from it. We were looking for something to get our 9 year old son to start taking piano lessons without having to buy a piano that would gather dust in a few years. The whole family enjoyed the keyboard. In fact, our children choose to play with it through video games and television. It has excellent sound, even without an amplifier, and is very easy to use. It has enough features to entertain our children for hours and still has the ability to sound and feel like a real piano for serious practice. It's worth the money.


  1. Just about any one will work,but it needs to have a “LINE OUT” plug
    in the rear. Line out plugs are constant low volume, as not
    to damage whatever you’re pluging into. Then you plug into
    the “LINE IN” in the sound card, at the rear of your computer.
    You will also need the elect.cord with the correct “ends” that plug into your piano (keyboard), too your computer..
    . Your retailer will help you.. Also you may need a mixing board to balance your tones.
