The example illustration of resultant sounds has an error "A440 on 2nd row" etc. This is a serious error that disrupts chain of thought process necessary to follow purpose. Should be A220, not A440. This is a very important discovery to me, one I have often thought was my own notion and want to learn it, therefore. Needs to be changed. Vinson alan (talk) 07:17, 18 January 2016 (UTC)vinson alan
