Broadway star and "The Voice of the Philippines" coach Lea Salonga took to Twitter to share an advice to singers. In a Twitter post on Monday, June 4, Lea tweeted, "Dear singers, please sing in your own voice's sweet spot. It might take some time to figure that out, but here's a hint: it's where sonic heaven and the limits of physical comfort meet, enabling you to create art." She added, "And we've not yet included emotional connection to this equation, but that's a whole other kettle of fish."
