I think the general idea is just great although I wouldn't pay $95 for it..maybe $10 or so per class is all...I think it sounds overly intellectual and technical for beginners...if you are just hoping to encourage newcomers to the hobby of group singing...the main thing is to do it...heave it out of you as they say in Newfoundland...guest instructors: you couldn't beat Stan James, Tim Hall, Chris Roe, Val Cohen, Janet Stecher, Joe Martin, to name just a few.
