When you sing, musical vibrations move through you, altering your physical and emotional landscape. Group singing, for those who have done it, is the most exhilarating and transformative of all. It takes something incredibly intimate, a sound that begins inside you, shares it with a roomful of people and it comes back as something even more thrilling: harmony.
The elation may come from endorphins, a hormone released by singing, which is associated with feelings of pleasure. Or it might be from oxytocin, another hormone released during singing, which has been found to alleviate anxiety and stress. Oxytocin also enhances feelings of trust and bonding, which may explain why still more studies have found that singing lessens feelings of depression and loneliness.
The benefits of singing regularly seem to be cumulative. In one study, singers were found to have lower levels of cortisol, indicating lower stress. A very preliminary investigation suggesting that our heart rates may sync up during group singing could also explain why singing together sometimes feels like a guided group meditation. Study after study has found that singing relieves anxiety and contributes to quality of life.
It turns out you don’t even have to be a good singer to reap the rewards. According to one 2005 study, group singing “can produce satisfying and therapeutic sensations even when the sound produced by the vocal instrument is of mediocre quality.”
Group singing is cheaper than therapy, healthier than drinking, and certainly more fun than working out. It is the one thing in life where feeling better is pretty much guaranteed.
