This is mostly a post to test that things work, but since we’re here: if you happen to have an iPad kicking around, Garageband (free download) is amazing. This is my 4 year-old getting properly absorbed by it. We had a lovely time playing with live loops and this drumkit sequencer, grooving away and chatting happily about repeated patterns, things happening at the same time, and other ideas all of which I’m happy to label ‘maths’ in the present circumstance. It’s not often you’ll hear me say positive things about STEAM ideas, but simple, discoverable and deep music interfaces like Garageband are where that concept really works for me.
