what do I teach at what intensity?
Scales are well beyond the typical young beginner, playing them is made difficult by the need for a thumb pass. Understanding them is made difficult by their general lack of exposure to music, and their "in the moment" approach to sound. They are not analytical, at this stage they simply couldn't care less about theory, they only care about whether its fun and sounds cool.. If you plan to get such material across you have to expose them to it as music and without theoretical understanding. Its like the karate kid, they learn the skills without realising, and when the time comes for understanding they will already have the skills and just have to make the mental connections.
I've always understood that the beginning stage is the most important stage for a student because all concepts and habits are formed at that time. So I'm surprised that the teachers here think this is a good idea. I read that this may be good for the student doing the teaching, because it's a good way to learn. But is it good for the child being taught? Would you like to have this girl as a transfer student a few years down the line?
