Stunning piece of art

I have built many of the Creator and Ideas series, and this is by far my favourite Lego build... period. The detail is exquisite: the counterweight key action with hammers, the dampers, the sostenuto pedal, the little lip on the edge of the keys, the little red 'felt' band on the keyboard, such attention to detail shines through every step. The amount of SNOT work is astonishing. You can tell this was designed by a pianist. Yes the building of the keyboard was a little repetitive, but I worked a system for rapidly building the keys. I agree with some of the reviews that it is not actually 'playable'. Come on, it's a Lego model, think what would be involved to add a sensor to every single key to actually play it. Perhaps slightly misleading of the way it's advertised, but not a reason to give 1 star. To the reviewers who complain about the motor making a noise - what do you expect, it's a motor. Some have said their motor and keyboard don't work and get stuck, I've not experienced that, and it resets to a flat keyboard absolutely fine. To the reviewers who give 1 star because it was out of stock -- ????? Hardly a product review. This is an amazing build - but I guess more so if you have an interest in pianos.

Bench is the Icing

This was my most enjoyable set build for a long time. While the piano itself was super interesting, particularly the authenticity of the action, something about making the lid was the most enjoyable. Perhaps because it was the final step, but simply in itself the lid was so elegant and true to life. The way the piano rolls around on the legs is also very satisfying. But all that was overshadowed by the bench. I hadn't expected it. Icing on the cake. A few steps into building the bench, it dawned on me that it adjusted up and down using a lifelike screw mechanism, I gave a big smile. How cool is that! Now I need to train a squirrel to play it.
