Review: Awesome Fun! - I have not done a nice Lego kit like this before, and looking through the construction manual, it looked rather difficult. However, my first impression was wrong. It was an easy build that was very relaxing and enjoyable. And yes, it worked great and there were no missing pieces. Easy to connect to the app and start. The keys, dampers and pedals move as the song plays. It is only two octaves of keys so no, the movement does not coincide with the music, but it is still an amazing build. It is a little rich in price which is a shame, but the Lego quality is evident in the pieces, manual and design. If it is within your budget, this is definitely one you would want to do.
Review: Fabulous Grand Piano Lego - This is by far the best Lego I have put together. It takes a little more concentration than some others, as you need to get it right the first time or you’ll be in all sorts of trouble reworking it! It actually plays 👍 It is a great showpiece.

## Questions & Answers

**Q: I am finding I put in new batteries play about six songs and the batteries are dead?  How long should the battries last.**
A: I can't answer this because I never used the electronics. I bought the kit to build as a present for my father who writes lyrics for Broadway. I can guess, however, that you might be using batteries very close to their use-by date. If they expire in 2 years, buy new ones. Also check that you are actually buying fresh batteries - their expiration date should be at least ten years in the future. Finally, make sure you get good quality batteries such as Eveready or Durcell. The band of battery does matter. Hope this helps.

**Q: What is the measurement between the legs?**
A: The distance between the two front legs is ~10", the outside of the two front legs would be ~11.5".  Front to back is ~10.5".  Hope this helps.

**Q: How many songs does the Lego app have for the piano?**
A: There was an update for the app and it now plays 20 songs...

**Q: how many steps are ther in all?**
A: The LEGO® Grand Piano has a total of 840 building steps! - Chelsea, LEGO® Customer Service

### ⭐⭐⭐⭐⭐ A Grandbaby Grand Piano
*by J***R on September 27, 2025*

The Lego Grand Piano was fun to build. It looks amazing as a display piece. I was disappointed that you can't play your own songs with the piano. The songs are pre-loaded music that play with the power-up app on the phone, and the keys move up and down. Some challenges with the bluetooth connection. The device inside the piano had to do an update that took several minutes. I had to look into what was going on as there aren't very clear instructions on that part. Overall - a beautiful Lego set to display
