G Dominant penta Scale
G Dominant penta contains 5 notes: G, A, B, D, F. The step pattern is W–W–W+H–W+H–W.
A stripped-down Mixolydian with only 5 notes and no half steps. It keeps the strong chord tones of a dominant 7th plus the 2nd for melodic movement, creating a clean, forgiving palette for blues-rock soloing.
The formula is 1, 2, 3, 5, b7. It removes the 4th and 6th from Mixolydian, eliminating all half-step intervals. With only 5 notes matching a dominant 7th chord (R, 3, 5, b7) plus the 2nd, it's as forgiving as the major/minor pentatonics but with a distinctly dominant flavor.
The shapes are comfortable and similar to major pentatonic with the 6th replaced by a b7. Use it over dominant 7th and 9th chords for simple, clean phrasing without the "minor pentatonic over a major chord" clash. Great for country bends and blues-rock double stops.
