Best Build Yet

This was a fun, challenging, and super rewarding build from start to finish. The LEGO Piano has a perfect mix of intricate engineering and beautiful design, and every section felt purposeful and clever. The moving keys and internal mechanics make it feel truly special. If you enjoy detailed sets that push your building skills while giving you an amazing display piece, this one is absolutely worth it! A real showstopper.

You will love this!

Having my own grand piano I had to get this. It’s a tremendous build that has all the main components of a real grand piano and its playing function is really fun. It would be cool if each key could play its corresponding note but it’s still quite fun to see the keys move on their own.

Must have for collectors

This is an incredible set to have. Actually slightly larger than I was anticipating. The build was fun overall, the keys were a bit repetitive obviously but still very beautiful. It’s probably a touch pricy but would definitely recommend!
