Donny ... Thank you for pointing that out ... I did not notice the pitch problems in the original recording ...
My concern about this is that there may be a more significant underlying problem ... I have had a punctured ear drum in my right ear since birth, but over time scar tissue has grown over the hole, compensating somewhat for the missing ear drum, and there has been only a small amount of hearing loss in that ear ... about 2 weeks ago I had a problem in that ear and the doc said that something - probably sinus pressure - blew out the scar tissue and now there is a big hole there ... I have an appointment tomorrow with an ear specialist, which will very likely result in some surgery to cover the hole ... Hopefully nothing has happened that will diminish my ability to detect proper pitch, or my 'career' may come to a sudden halt ...
