12-Bar Blues Form & Structure
Welcome to this introduction lesson to the 12 bar blues. If you are new to the blues this lesson will teach you the basic harmonic framework,
Triads, 7th Chords, & Inversions
We first voice the chords first using basic triads and then we extend the triads up to the 7th degree to create seventh chords. When playing blues, jazz, and other types of improvised music, 7th chords are required to create smooth voice leading in the harmony.
7th Chord Inversions
Once that you are comfortable with the root position 7th chords we can invert them which creates smooth voice leading possibilities between the I, IV, and V chords in the blues.
Using 7th chord inversions allows us to transition between the chords with minimal hand movement which results in more control and a more balanced sound when playing through the basic harmony of the 12 bar blues.
Isolate The 3rds & 7ths
Finally we play through the form using just the 3rds and 7ths of each chord which are the most important tones from a harmonic standpoint. Isolating the 3rds and 7ths is an important drill to clearly visualise the voice leading between the chords of the blues.
Once this step has been mastered we can introduce more interesting tones such as the chord extensions and chord alterations that we cover in the upcoming lessons.
