Music Theory Part 9 – Minor Scale 4 Note Chords

June 2, 2014 9:46 am Published by Leave your thoughts

Welcome to Part 9 in our series on Music Theory.  This time it’s about Forming 4 note chords in a minor key.

This is where we refer back to the post about Relative Major/minor scales and keys, and 3 note chord formation: Major and minor.

In exactly the same way that we would jump to degree 6 of the Major scale to begin the minor scale,

eg.  Major  C   D   E   F   G   A   B
minor  A   B   C   D   E   F   G

We can do the same when extracting 4 note chords.

ie.  The formula for 4 note chord types in a minor key is the same as in the major key starting from step 6

Therefore,  Major Key –     Imaj7     IImin7     IIImin7     IVmaj7     V7     VImin7     VIImin7b5

minor key –     Imin7    IImin7b5  IIImaj7     IVmin7    Vmin7  VImaj7    VII7

 

It is important to learn and know these formulas from memory and independently of each other.  Their relativity is purely something to fall back on if you forget something about them, and something to understand of their origin.
