Watch the Altered online guitar lesson by Chris Buono from Modes That Matter

As crazy as it might seem the altered scale has but one purpose and one that it does real good--deeply color dominant chords in a V-I situation. So much so for the first time we’re going to adopt a new approach to playing scales that are meant for V7 chord tension. The next two segments as well as the ones for Phrygian Major, wholetone and symmetrical diminished will feature jam tracks where the changes will not be static and cannot be approached horizontally. That’s right folks, you’re gonna be playin’ over changes--just two though.
