Intervallic Formulas for Modes

Modes are often taught as intervallic formulas. The intervallic formula changes depending on which scale degree is functioning as the root. For example, and using the G major scale, if the ii chord Am is functioning as the root (as in “Oye Como Va” by Santana) then your ear hears everything in relation to A, not G (in fact G becomes the 7th). Count your intervals starting from A and you have the intervallic formula for Dorian mode (1 2 b3 4 5 6 b7). But the notes and patterns remain the same as G major.

With guitar modes you don’t have to learn new patterns or alter the patterns you already know. You just have to understand which scale degree you’re playing around.

I walk you through all seven major scale modes and demonstrate how to use modal scales and create modal sounds in my DVD, Guitar Modes – The Modal Scales of Popular Music. Sign up for a free preview at:
