⚠️ READ THE ONE STAR REVIEWS BEFORE PURCHASING! ⚠️
on August 7, 2025
Posted by: Zero Cool
Verified Purchase:No
I actually only gave this set five stars in the hopes that some of you loyal LEGO customers won't miss the negatives regarding this set, and wind up wasting your time with it. And so, here are those negatives...
The piano itself does not play any music. The sound of the music comes out of whatever device you are using with their Powered Up app. And no, you can't create your own music or choose your favorite songs to be played. The app has two modes, 'Listen' and 'Play.' And even after all of this time, the 'Listen' mode has 20 songs to choose from, and the 'Play' mode has 9 songs to choose from (at the time of this review).
Now, for the 'Listen' mode, the piano keys automatically move as a song plays. However, if you are under the impression that the keys move while matching the right music notes, then you will be disappointed... No, it looks like the keys just keep moving in the same order, to give the impression that the piano is playing the music.
As for the 'Play' mode, you can't really play the actual notes in the songs like you might expect to. Because the way that it works is that you just press any key and it triggers the next sound in the selected song. And the reason that it works that way is because there's just one optical sensor that detects when any key is pressed.
Now, putting all of that aside, this is still an extraordinary build and a lot of fun can be had just building it. And it might be a little challenging for some builders. Also, some builders should consider that it's possible they have made a slight mistake somewhere even if they are absolutely sure that they haven't. I know, because it has happened to me a few times over the years, lol.
But anyway, my conclusion is that LEGO could have saved themselves from a lot of negative feedback if they had just provided more information about the things that I just mentioned. I mean, that's what I mainly wanted to know about this set. And I'm willing to bet that's what a lot of other people mainly wanted to know about it. But don't worry LEGO, I still love you! I just hope y'all can someday convince Paramount to let y'all make Star Trek sets before this human vessel that I'm inhabiting reaches the end of it's lifespan, lol...
No, I would not recommend this to a friend.

Wonderful detail, iffy mechanics
on August 2, 2020
Posted by: OtterPuff
I guess I lucked out and hit my local Lego store at the right time to purchase this Grand Piano. I saw it advertised on a classical FM Facebook page and knew I had to get it. Construction was smooth, if a little tedious due to the repetition of making 25 working keys. The overall look of the piano is amazing and true to detail. My only complaint is in the mechanics. The motor doesn't always turn the spindle for the key movement and will get stuck. There is a function to reset the keys to a neutral position and that doesn't work. The motor also has a very high pitched whining noise that takes away from the enjoyment of the music. Regardless, i highly recommend this model if you can find it.

To all the haters of this set:
on March 11, 2021
Posted by: Mastrhylia
You guys all say that this set is stupid because you can't actually play the piano. Well, in the specifications it CLEARLY states that you can "Pretend to play along". It literally says that you can't actually play the song with the keys, you PRETEND. Also, from what I know, it would be quite hard to make the keys periodically play the actual notes. There aren't enough keys on the piano to do that, so it would have to be way bigger. It's not very fair to condemn Lego when they have tons of amazing sets. Yes, there are some flaws, but it's better than I, or most anyone could do. I also think it's dumb for you to just go through and click on one star for everything. You say you have many sets, but you put one star on your play experience. Give an honest report for the people who are actually wondering if they should buy this set.
I would recommend this to a friend!

Amaaaaazing!!

We have room dedicated to Legos in our home and my husband and kids are Lego fanatics. Yet, this was MY first set and I absolutely loved building it. I'm a musician by trade, a pianist and band teacher teacher. I love the detail and I loved seeing it come together. I purposely took my time to build this to savor all the fine details. I'm in awe. I do have one complaint, why don't they use the correct written music in the app? They have the music on the Lego part that sits on the piano, but none of the songs actually match what is being played in the app. This seems like a small detail that was overlooked and can still be remedied. Everything else is better than hoped for.
I would recommend this to a friend!

Well constructed and good looking
on June 3, 2021

This is a wonderful LEGO addition. The build was a bit repetitive, but it's a piano so that should be expected. I do have two suggestions. [1} the LEGO software is very difficult to shut down. I had to turn off my I-phone12 to get the program to stop running. [2} serious suggestion: The wheels should be gold. Look at the the picture of the real piano in the instructions. The wheels are bright brass. In the model they are black and there is plenty of that already. Gold colored wheels would set this model off a lot. If you decide to do this, send me a set of wheels!

Great display and workable set

For those who wrote just a one or two star review, remember, this is a toy, don’t expect features that you would normally pay hundreds more for in a real piano, like playing specific notes, keys really sounding a tone, keys moving exactly to the music, etc. Lego has built this as a fantastic toy and it does a splendid job of MIMICKING a real piano, be thankful for the tunes and engineering that went into the product! If you want something that can do most of the features of a real piano, GO BUY ONE ! And btw, I am an accomplished pianist (I have a Yamaha Clavinova).
I would recommend this to a friend!

A joy, a tragedy, back to joy

I completed the piano some months ago. Ready to attack the bench to finish the project, I sat the piano on a tray table just to fool with the mechanics. Open the lid, hit some keys, fold back the music stand.
To my horror, I watched the piano roll off the table (it has swivel wheels that work VERY well), flip over, and hit the floor. It wasn’t completely smashed but mostly smashed. I gathered up any intact sections and all the individual bits I could find.
And put it all away. I was heartbroken and just didn’t feel the energy to dive right back in.
I left it for months.
Just this week I got up the courage to bring it back to life. Some sections needed to be torn down to single pieces and rebuilt from scratch.
Which was fine because I remembered how much I enjoy building this stuff!
So, piano, and bench, are complete. AGAIN.
It’s a fantastic build, and an engineering marvel. Hours and hours of joy. Heartache too, but that was all my fault.
Now, I’m looking for the next project. My wife has firmly rejected The Titanic. Rats!

Great kit…looks tremendous
on May 24, 2022
Posted by: JDSthebuilder
I really enjoyed building the Grand Piano. Instructions were clear and easy to follow. Final build looks just tremendous! Yes…it is not a player piano but a complex kit that does mimic a real piano. Those who say it is not a real piano need to understand that 25keys does not a real piano make! That being said…the keys and hammers do work…the music selection is cool and the Lego PowerUp really does work. I am speechless at the engineering that went into this! Well done Lego!
