Ah, you know me, I’ve seen the old kettle sing a lullaby that made a whole row of strangers tap their feet like they’d just had a good laugh. Those “booster” tunes? They’re the ones where the melody takes a breath, the rhythm catches its own breath, and the crowd’s nerves unwind. Just don’t let a metronome keep you from that wild, off‑beat groove, or you’ll kill the spirit of the song. Keep playing what feels like a sunrise on a porch, and the immune boost will follow in the form of smiles and dancing feet.

Yeah, that’s the magic, right? A tune that jumps a note, throws in a swing, and the whole crowd starts breathing a little easier. Imagine that kettle I’m always carrying—says “don’t crank up the same old chord twice,” because that kettle sang its own little anthem back in ’76, and it was the first thing that stopped a whole room from falling into a lull. So when you hit that unexpected shift, the body’s like, “aha, we’re not stuck,” and the stress hormones take a holiday. Keep rocking that surprise, and you’ll get a chorus of good vibes and maybe even a few stronger antibodies, all while the audience thinks they’re just having a good time.
