There have been a few remarks about the teacher Accreditation Scheme run by prominant members of the British harmonica movement. (Chairman, ex publisher and editor of Harmonica World, Organiser for the British harmonica Day)
I fully support this idea. Whether or not you approve of a formal education for harmonica players this scheme is a start towards making certain that harp teachers do know what they are talking about. I have a fair amount of knowledge about the harmonica but I think, if I remember what Colin Mort told me (and Steve Jennings) I would have to do some research before I could answer the questions!
Any scheme has administrative costs, It costs about fifty dollars to get an electrician into your house before they start doing anything these days. Fifteen dollars seems to me to be a totally reasonable charge. How long would YOU work for for fifteen dollars. A chiropodist would give you about 5 minutes!
No, I am not involved in the scheme and am not accredited by it. This is laziness on my part and the fact that I tend to get pupils who want my teaching for particular reasons. But it does mean that my name would not be on the register of teachers. One lesson from ONE pupil would leave you in profit on the deal!!
