Official Details of 21323 Grand Piano

As you may have guessed from the LEGO Facebook teaser, it’s time to officially unveil the final product version of the LEGO Ideas piano.

Introducing 21323 Grand Piano

$529.99 – Available August 1st


Coming in at 3,662 pieces and measuring 22.5cm high, 30.5cm wide and 35.5cm deep when closed this is a big model.


That large size has allowed the designers to integrate Powered Up elements, taking this model from a display piece to something that you can interact with. You can either play a tune yourself or put it on automatic mode. This interactivity is created with a motor, hub and a sensor element. Obviously you will also need a compatible smart device.


While the original Ideas submission featured strings I think the Powered Up approach is an interesting one. It does drive the price up though.

I’m not a very musical person so this one isn’t going to make my must have list but I’d love to hear your thoughts. Let me know in the comments if this is one you’ll be grabbing.

The full image gallery and product description can be found below.

    Hmm, I would prefer to be able to buy one without the powered up stuff. Im not gonna use it and it adds a huge amount to the price. Well, Im sure bricklink will provide, in that regard.

    Looks like another set Lego have knocked right out of the park. I’ll sit it next to my Osprey. Oh wait …

    This is one I was really looking forward too but I feel that the power up was not necessary and makes the price disappointing. I just wanted it for display, not play.

    Thanks for posting this article so quickly. I purchased a real grand piano for my wife 25 years ago for $2,500. I’d love to buy her this one just for fun, but at $530 it’s an easy pass. I’m not interested in the power-up functionality and think it would be great if Lego gave you the option to buy it with or without it. I’d definitely buy it for $350. It would make a great anniversary present!

    That’s a ridiculous price. A pass for me. $530.00 ????? Is Lego serious???

    I love this. I personally think it is stunning. While I like the novelty of the Nintendo set, this is something I would prefer to display.

    While its pretty cool, you can buy a real piano keyboard for that price or a tad more so…

    My main disappointment is that it seems to be all smartphone based and ultimately the piano doesnt actually do much. I really wish the individual keys had had sound bricks behind them for each note so one could actually play it.

    Its also very blocky in its shape, I know that was necessary but it does look like a grand piano that someone put in front of one of those fairground mirrors.

    Im also rather annoyed by the advertising which is very similar to that of real pianos thereby suggesting this is in the same league as a real piano… The fact that they used some random modern song in the promotional video was ridiculous; your advertising a piano but use music that doesn’t even have a piano in it! At the very least one would think they would have proper piano music in the demonstration of the smartphone app working with the model like in the teaser video.

    I find the advertising for this to be very misleading as you can’t play a tune that is linked to the particular keys you are touching. I don’t know why they are implying that you can, with their wording.
    It is a beautiful set and fascinating to see the inner workings. Congratulations to the designer on a brilliant job.

    Now Lego is supporting the ivory trade! This set should be withdrawn from sale immediately!
