Watch the Practicing Blues Scale Voice Leading online guitar lesson by Jason Loughlin from Blues Connections: Minor
The same concepts and drills apply to voice leading the blues scales as they did to the minor pentatonic. This performance example is over a 12-bar blues in A minor. You'll need to know mode 1 in A minor, mode 4 in D minor, and mode 3 in E minor. Run this drill for the remaining four positions.
