I ordered Brett Manning’s Singing Success vocal programme today. In his “Philosophy of Learning” section he writes:

Have you ever seen the movie Karate Kid?  Singing Success uses the same “wax on, wax off” approach to learning.  You’ll improve steadily by doing simple exercises that retrain your muscles to automatically respond with new coordinations. 
That’s exactly what you do with Genki English. The kids think they are simply playing games or singing songs, but what they’re actually doing is getting really good at English. The added advantage with being Genki is that waxing on and waxing off isn’t a chore, it’s actually really fun!

Try learning some German or Japanese this way, you’ll find it works for anyone.

If you want to know how Brett’s course works out, I’ll let you know in a couple of weeks…
