Have you had the experience of walking into a rehearsal with a new group of people and immediately listening closely to determine who is the best singer?
Do you find yourself classifying other singers in your head, so you know where you fit in?
Does your opinion of someone change after you hear them sing the solo/aria/whatever?
Do they go up or down in your estimation?
Just imagine, you show up at a singing masterclass….you sit down and the person next to you...
