I have to apologize to Mrs Shewell. I did not mean disrespect. I am very grateful for her time she gave to me the other day. I have found that there must be at least two entirely different physiologis producing timbre commonly called ¨falsetto¨ This explains much. My own falsetto (and Ian Gillan's too I believe) is the most powerful on the top, no sign of breath and my apple stays down regardless of pitch. Also the vibration I feel much higher in the throat. It denies a lot what many including Mrs Shewell say about falsetto
