Review: Yamaha YPG-635 88 Key Weighted Portable Grand Piano

Combine a great sounding piano sound with attractive wood finish and then add in a host of useful and advanced features, the Yamaha YPG-635 88 Key Weighted Portable Grand Piano might just be the perfect portable digital piano for you. After this review, you will know significantly more about the YPG-635 including its pros and cons and other important considerations you should be aware about. So let’s get started with the review of Yamaha’s flagship consumer digital piano…

The Yamaha YPG-635 model comes with standard 64 note polyphony, a two-way speaker system (separate woofers and tweeters), a handy digital display, a multi track recorder, built-in reverb effects and digital signal processing (DSP) which adds different special effects.

If that’s not enough, Yamaha also throws in a fully adjustable metronome which is great for anyone taking piano lessons. You also get a total of 130 voices, 12 special effects and drums kits, and 361 XGlite voices — that’s quite an impressive list of voices and features for a piano of this modest cost.

Yamaha YPG-635: The Good

For me, the big selling point of the Yamaha YPG-635  is the piano action provides; it’s very similar to a real piano. Just like a real acoustic piano, the weighed hammer standard action keys enables responsiveness and a touch that feels heavier on the low parts and lighter on the high notes. Every time I play this model when I see it on display in a music store I’m always blown away by how fun it is to play.

Equally impressive is the pleasing quality of the grand piano sound which is all made possible by Yamaha’s proprietary Advanced Wave Memory technology which produces exquisitely realistic sounds. What makes the sound quality even better is the digital signal processing which enhances the overall sound quality of the piano and takes it to the next level.

I can’t let this review go by without mentioning the attractiveness of this model. The neutral wood accents really make one of the most attractive portable pianos I’ve seen in a long while and make it the perfect addition to any room.

Yamaha YPG-635: The Bad

Sometimes I found myself overwhelmed by the sheer number of features the YPG635 has. As someone who just likes to sit down and play the piano it can get overwhelming. However, once you read the manual and figure out what each button does you’ll have no problems. Note: for those that just want to play the piano you can press the Portable Grand button as shown below in the image.

Another possible downside for this model would be its small display which can be quite of a hindrance to those who are relying on the display for digital sheet music while playing. Sadly, there is no available option to make it bigger.

The volume of the speakers might actually become a disappointment to those who want or need to play with the YPG-635 in front of a live audience. Most of the time, you might need to set the keyboard volume to maximum unless you can use external amplifiers.

This Digital Piano is Perfect for:

  • beginner piano students as you can:
    • read digital sheet music on the display
    • record your practice sessions
    • use the built in metronome
  • accomplished musicians who want the sound and feel of an acoustic piano without paying the high cost
  • someone with limited space in their home or apartment as this attractive portable piano can fit practically anywhere

Final Verdict

Overall, the Yamaha YPG-635 88 Key weighted portable grand piano is a terrific buy considering its realistic grand piano sound and authentic piano action. It’s less expensive than the newer Yamaha DGX-630 which is essentially the same piano!

Bottom line: when you take into account the numerous features that Yamaha has packed into this piano, nothing can come close. Somehow Yamaha has found that elusive sweet spot of sound, action, features and price. That’s a remarkable achievement in a very competitive market.

This model scores so amazingly well on every criteria that I don’t hesitate to give the flagship Yamaha YPG-635 top marks all around. So when it comes to looking for a great portable digital piano for a reasonable cost, this particular model should be the first model on your list to consider.

A YPG-625 Owner’s Review

By J. Denton

Wow! I couldn’t be happier with this keyboard. It feels and sounds just like a real piano, not to mention the other 500 sounds you can get from it. We were looking for something for our 9 yr old son to start piano lessons on without buying a piano that might just gather dust in a few years. The entire family has been enjoying this keyboard. In fact, our kids are choosing to play it over video games and tv. It has great sound, even without an amplifier, and is very easy to use. It has enough features to keep our children entertained for hours and yet still has the ability to sound and feel like a real piano for serious practice. It is well worth the price.

Here’s a great video that demonstrates the classic Yamaha grand piano sound and shows you all the features of the pedals:


  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.
