Hy Matt,

I’m really glad you found this at your age. I started playing when I was 15 and struggled with this for 30 years. Rote-memorization was the only method around at the time. Thanks for ETH, I really appreciate it. Be sure to check out The Rosetta Pattern for modes and scales. It will give you a solid foundation for further learning. I’m still working on my next book on Intervals and Chords and your contribution will really help!
