I've learnt new scales through playing different types of music, like Indian raga scales, gipsy scales and harmonically-based jazz scales.
I took group lessons at a rink near my home. We first had to learn how to stand up on the ice wearing skates. Eventually we learned to move forward, but soon found out that it was not that easy to stop! So that was our next important lesson.
Back in those days intimidation was the greatest tool the drill instructor had. Without that tool, he would not have had control.
