I've been following Ken's lessons for a few months now. Prior to his lessons, I was following Eric Arceneaux, another vocal coach. He was helpful, but after watching Ken's lessons, I noticed that he never really demonstrated the stuff he was talking about in his singing, and he didn't really have any students demonstrating it either. I've noticed significant change and improvement since taking Ken's lessons, but recently a parent has told me that voice sounds rather monotone. Could this be because I'm singing too low, or am I doing something wrong? I would love some feedback. Thanks, guys. Keep singing!
