We know this already, but it's always nice when neuroscience backs us up: Performing in a musical ensemble is good for your health. Researchers in Sweden have come up with a biological explanation of how singing in a choir lowers your heart rate. And Stacy Horn spends a lot of her new book Imperfect Harmony: Finding Happiness While Singing With Others explaining why being part of a chorus changes your brain chemistry, for the better. We're not jealous that choral singing has the spotlight right now. There's every reason to believe people who perform in community bands enjoy the same benefits.
