Hello everyone,

I am diving deeper into theory and practical application on the guitar. Right now I'm focusing on learning how to harmonize lead lines with 3rd and 6th intervals. My issue is that I'm a very visual learner, so I would like to see some diagrams.

All over the internet, you can find diagrams of scale patterns and chords. However, here on guitar tricks or anywhere else online, I have not seen patterns that just highlight patterns by intervals.

For instance the A major scale shown, but highlighting all third intervals in the scale. Then I could take that pattern and practice it in every key. Also, I'm referring to all of the thirds relative to one another, not just the root and the root's third. Does anyone know where such a resource could be found? Thanks!
