Dominant 7th Chord - Concept 7 is a video guitar lesson presented by Andrew Ford and is sourced from Blues Bass Survival Guide.
A chord type used extensively in the blues is a 7 chord or dominant 7th chord. This chord is made up of the root, major 3rd, 5th, and b7 and is written with the root name followed by a 7, for example E7 chord. For a 12 bar blues in C for example, the 1 chord would be C7, the notes would be C, E, G, and Bb. Let's familiarize ourselves with the sound and components of this chord with six exercises using only the notes of this chord. We will also incorporate a simplified 1-4-5 progression. Remember each of these patterns should be transposed to all 12 keys for maximum benefit.
