No doubt. You learned the sound the scale makes instead of 1-4 1-3 1-3 1-3 1-4 1-4 Bottom line is you ended up in the same place. So in effect, you really did learn the scale and then some.. Regarding lessons.. Up until a couple years ago, I never thought I would benefit from lessons. I was always self paced self taught type. Then I became frustrated in playing the same old same old.. and I wanted more... But rather then downloading yet another course I wouldn't finish, I contacted my current teacher.. While I have not been an every week kind of student I do find once in a while being very helpful. It is because I get to ask him things and learn techniques that are much easier with him there then it is with a computer video.
