Arguably the world's most accomplished and enduring a cappella vocal group, the King's Singers speak eloquently on the lifelong benefits of singing:
“There are multiple studies to show that people who sing live happier, richer lives. They become better able to communicate. They become more employable. It makes their brains work in a way that helps them to fulfill cognitive reasoning elements and to learn languages. … It’s just a recipe for brightening up your life generally,” he says. “I think people are seizing on that as being part of living a healthy, active lifestyle.” via The King's Singers | Hoopla.
