Whenever I start singing and encourage others to sing with me, I will begin with a hum - a gentle hum. Because anyone can hum. And it’s a nice feeling - humming to yourself, getting the vibration going. It’s good for you, it warms up the soul. And then, quietly, when no-one is looking, I invite you to open your mouth. Hmmm Ahhhh..Hmmmm…ahhhh.
