Let’s face it: when you imagine your next big Lego set, a piano probably doesn’t spring to mind. Those instruments are complex beasts, seemingly unsuited to being replicated in plastic blocks. Yet Lego Ideas Grand Piano (£319.99; available 1 August) genuinely gives you a 3662-piece brick-built grand piano you can set on a desk. Its 25 dinky keys might not mimic the number on a real grand, but there is a top-lid to prop up and moving pedals. Most importantly, there’s an authentic hammer action and fully working keys, so you can unleash your inner Beethoven (or, more likely, attempt Chopsticks in a halting manner). But it’s still just plastic, right, and so merely makes a dull thud when you hammer away at its two octaves? Not quite. Combined with Lego’s Powered Up app, you can use this piano to play actual music – albeit only triggering the next note in a song by pressing any key. If that sounds like too much effort, select a song and the piano will play itself.
