F Major Jazz Chord Progression #1 on Strings 1 - 4

Here's a jazz chord progression I like:

F6 /  F#Dim7 /  GMin7 /  C7b9 /  F6

Here's what it sounds like:

Here are the chord diagrams:
 
F6 means F sixth.
F#Dim7 means F# diminished seventh.
GMin7 means G minor seventh.
C7b9  means C seventh flat ninth.

This is a variation of the ii - V - I chord progression.

I (roman numeral for one in upper case letters) represents the major chord based on the first tone of the major scale.

ii (roman numeral for two in lower case letters) represents the minor chord based on the second tone of the major scale.

V (roman numeral for five in upper case letters) represents the major chord based on the fifth tone of the major scale.

In the key of F, F major is the "I" chord, G minor is the "ii" chord and C major is the "V" chord.

It is very common to make the V chord a dominant seventh chord.

In the chord progression at the top of this post I substituted F sixth for F major, G minor seventh for G minor and C seventh flat ninth (no root) for C dominant seventh.

I added a F# diminished seventh chord between the I and ii chords. Diminished seventh chords can sometimes be used in transitions between chords.

You probably noticed that the 7b9 (no root) chord looks like the dim7 chord at a different fret. These two chords share the same tones.

I'll be writing more about how these chords are formed in upcoming posts.
