The set also pushes boundaries of design and functionality and becomes the first ever LEGO Ideas set featuring Powered Up functionality, to enhance the piano experience even further by allowing you to play a tune or play one automagically.

The piano, which measures over 8.5” (22.5cm) high, 12” (30.5cm) wide and 13.5” (35.5cm) deep when closed, will without a doubt turn some heads, as both a display and playable piece.

The original concept model, submitted back in 2018, which won the hearts of LEGO fans around the world was created by Donny Chen, a piano teacher himself and our very first Chinese Fan Designer. You can learn more about Donny in his earlier 10K Club Interview. To pay tribute to Donny and a song that he composed, which he featured in his promotional video for his original Product Idea, a printed element with his name and song accompanies the Grand Piano set.

Donny's fantastic concept model was given the LEGO treatment by LEGO Designer Woon Tze Chee with support from LEGO Designers Steen Sig Andersen and Sam Johnson, with graphic design by Crystal Marie Fontan.
