I teach English Jeri - nobody has ever asked me to teach songwriting!
However, I do agree with the comments about teachers needing to be able to make students more confident. I am very careful not to say or do things which could attack someone's confidence. Any damned fool can make people feel stupid or embarrassed - and that just makes it more difficult for the student to learn. Speaking as a teacher, I like people who ask questions. It shows they are interested and trying to get more from the class. That is gratifying for me too. I always encourage students to challenge what I say. If they think I am wrong it may well be that they have not yet grasped a principle (possibly because I have not made it clear enough). On the other hand, it can happen that I am wrong and the student is right. If the student corrects me, they are doing us both a favour!
