I'm wondering why patterns are taught instead of teaching intervals. I learned the pentatonic patterns but had a really hard time connecting them. Plus I could never tell where the root was. Then I was worried I'd have to learn new patterns for the major/minor scales. Once I started thinking about it from an interval perspective it was very easy to figure out where the root was located and how everything connected. Plus switching between minor and major in different keys is much simpler. So what is the reasoning behind teaching patterns instead of intervals?
