The minor 7 chord is simply the minor chord with the 7th note of the natural minor scale added.
Let’s use the C minor chord to show this:
C Minor
C Minor 7
Minor 7 Chord v 'Relative' Major 6 Chord
Every minor scale has a relative major scale.
The diagram below shows that the C major scale is the relative major scale of the A minor scale and both scales contain the same notes:
The minor 7 chord and relative major 6 chord contain the same notes
This rule applies to all other minor 7 chords for example:
[E minor 7 & G major 6], [B minor 7 & D major 6], [C# minor 7 & E major 6] etc..
Let’s use the A minor 7 chord and the C major 6 chord to show this:
A Minor 7
C Major 6
Chord Formula:
A minor 7 chord is made up of notes based on the intervals of the natural minor scale.
The minor 7 chord formula is 1-b3-5-b7 (i.e. the Root,b3rd, 5thand b7th notes of the natural minor scale).
Inversions:
An inversion is simply a way of identifying when the notes of a chord have been ‘inverted’ i.e. when the root (1st) note of the chord is not in the lowest (bass) position.
For example:
The A minor 7 chord consists of 4 notes, A, C, E, G (1st–b3rd–5th–b7th).
When the lowest note of the chord is A (1st) then it is in the ‘root position‘.
When the note C (b3rd) is in the lowest position then the chord is known as a ‘1st inversion‘.
When the note E (5th) is in the lowest position then the chord is known as a ‘2nd inversion‘.
When the note G (7th) is in the lowest position then the chord is known as a ‘3rd inversion‘.
The inversion is determined only by the note in the lowest (bass) position, it does not matter what order the other notes are in.

The diagrams below show the generic CAGED shapes for minor 7 chords.
The indigo note is the root note of the chord, for example:
– if you wish to play the D minor 7 chord then the indigo root note will be the note of D, for example, the ‘E’ shape for D minor 7 is at the 10th fret, the ‘A’ shape for D minor 7 is at the 5th fret.
– if you wish to play the F minor 7 chord then the indigo root note will be the note of F, for example, the ‘E’ shape for F minor 7 is at the 1st fret, the ‘A’ shape for F minor 7 is at the 8th fret.
