The lydian dominant scale is great scale to learn as it brings out a very characteristic color or sound.
This scale is built as followes:
In the key of C... C D E F# G A Bb or root ,2nd, 3rd, #4th, perfect 5th, 6th and b7
It is primarily used over C7b5 chord C E Gb Bb or root, 3rd, b5th, b7th (D7b5, second chord in Duke Ellington's "Take the "A" Train).
G, A, Bb, C, D, E, F# or root, 2nd, b3, perfect 4th, perfect 5th, 6th and 7th So you could say that the C lydian dominat scale is a mode of G melodic minor built off it's 4th degree (they are interchangeable or relative).
It also works well over C7aug11... C, E, G, Bb, D, F# or root , 3rd, 5th, b7th ,9th and #11
Parallel then means: same starting letter(C) but different key signature. 2 flats Bb and Eb or the Bb major scale. The dorian mode is used to improvise over minor 7th or minor 6th chords. Typical progression would be Cm7 to Dm7 use C dorian.
A great new distortion pedal out on the market that I recently discovered is the John Suhr "Riot Distortion".
I have a few openings for Guitar or Bass instruction in my Lake Worth studio or via Skype.
