I’m not sure how I missed the existence of this – a metronome that you can wear? The Pulse by SoundBrenner is a haptic watch-like metronome that you wear on your wrist to keep time. You can give everyone in the band one and sync them up like you’re James Bond (ok, you’re probably more like Moneypenny, which probably makes me Q, but I digress), which means that no one has an excuse for playing out of time. There’s also a body strap version that you can wear like a workout heart rate monitor if you prefer to feel the beat near your heart!
Have you tried one of these? Let me know in the comments how it’s working out for you and your band
