If you were anything like me, you hated to practice scales when you were a kid taking lessons. I couldn't see any possible use for playing scales, or even knowing them.
Boy was I wrong!
Without scales I wouldn't have a clue how to form chords, improvise, make up fills and riffs and so on. Plus I wouldn't have the technique to play what I need to play.
So thank heavens for my teachers who drilled scales into me.
