The LEGO Ideas Grand Piano (21323-1) enables the assembly of the first playable LEGO concert grand piano. This 3662-piece model faithfully replicates instrument details, including a top lid that props open and a fallboard. Technic mechanisms drive the hammer action of each key and activate a pedal with movement. Integrated with the LEGO Powered Up app, the piano supports user play for direct note activation or an auto-play function for melodies. This brick-built replica offers engineering and musical artistry as a display piece.
