Bit of a jazzy one today. This progression follows a chromatically descending movement, as the bass notes of each chord are only a semitone apart. A very common feature of jazz progression.
Now, you may or may not know what chord inversions are, but we use a couple in this sequence. Basically, a chord inversion will include all the necessary tones that make up a specific chord, but the root note isn’t the bass note anymore. Think of it like re-ordering the chord intervals. For example, in the first chord (A major), the major 3rd is the bass note, giving it a completely different sound. More unstable than a standard root-5th-3rd barre chord shape.
From this unstable chord, we fall down the fretboard, through another inversion and other movable chord shapes typically found in jazz. You’ll notice only 4 strings are used for each chord – these are often referred to as shell chords, although there are different interpretations of what tones shell chords can/can’t include.
Anyway, take a listen and hear how it naturally collapses into that safe tonic chord of Amaj7. It’s all about tension – resolution!
Remember, these chord shapes are movable, so you can move them up and down the fretboard keeping their formation.
We’ll be sure to visit jazz again some other time : )
