M5 - Project  2 - Substitute Chord for your rhythm/strum

Using the minor 6th or the 9th Chord

A - STRUMMING ALONG IN THE JAM-ROOM

In M5 Project 1 we have been looking at Jamming in the Jam-Room using our Pentatonic and Blues Scales over the CTB Blues Bop VIDEO files, keep doing this in all keys to perfect your soloing.  (Many more files will be added too)


Now we want to look at strumming along with the 12 CTB Blues Bop VIDEO files and using some slight variations, by using a substitute chord in parts.  The minor 6th or 9th chord (Note: They are very similar)

B - ALTERING AND ENHANCING THE CHORD PROGRESSION

Let us look at the chord progression CTB Blues Bop in A BELOW (Diagram 1)

Each bar there is one chord, and each chord-bar is basically 4 beats.

So to make it a bit more interesting when strumming along we can use a substitute chord

For example, LOOK AT Bars 5 and 6, instead of playing two bars of D7, we could play D7 for bar 5 and play a D9 for bar 6 (Diagram 2)  This makes for a variation


E - MOVABLE CHORDS


Remember all these chords are movable

So a D7th chord moved up the neck as shown below becomes an E7th chord etc..


So you can substitute a D7 chord with an A minor (D9th)

You can substitute an E7th chord with a  B minor (E9th)

You can substitute an Eb7th chord with a  Bb minor (Eb9th)  etc…

DIAGRAM 1

DIAGRAM 2

Know these chords well as they are very good substitute chords

(Normally I only play the minor 6th shape)


The 9th chord formula is 1 - 3 - 5 - b7 - 9=(2)


The minor 6th chord formula is

1 - b3 - 5 - 6


If you are not familiar with chord formulas then you need to first go to Easy Practical Theory now OR Download the free app Easy Practical Theory and study this module


And also go to Guitar Chords for Beginners and study this module

or Download the FREE App Guitar Chords for Beginners app  It is App number 2


Also refer to M2 Project 3a

C - THE 9th CHORD and the MINOR 6th CHORD

The picture 1 below shows a D9th chord covering the 4th and 5th frets on the guitar

(The Tonic note 1 is D)

The picture 2 below shows an Aminor 6th chord covering the 4th and 5th frets on the guitar

(The Tonic note 1 is A) The 5th string will be dead (Not played, dampened by the 2nd finger touching it)

Notice the similarity between the two chords, you can use either for your substitute chord

D1 - THE A MINOR 6th CHORD VIDEO and D7 CHORD CHANGES


1 - Practice the A minor (D9th) shape chords till you are totally comfortable with that basic shape


2 - Then practice changing from the A minor (D9th) shape to the D7 chord shown below

You want to be able to change quickly from one to the other and back again

Then play along in the Jam-Room using the D7 and A minor (D9th) shape

All these chords are movable chords, know them well


X X D 7 Movable Chord

D2 - THE AIM

The aim is to be able to play 4 chords in One Bar of music


So instead of playing 4 beats of D7 in one bar, you can play

1st Beat D7    2nd Beat A minor (D9th)   3rd Beat D7   4th Beat A minor (D9th)

When you can change that quickly you know you have mastered the changes

F - USE THE JAM-ROOM


Go to the Jam-Room and start of by doing the substitute chord progression shown at the top in  

( B - DIAGRAM 1 )   Using the chord progression CTB Blues Bop in A


Instead of playing two bars of D7, play D7 for bar 5 and play  Aminor6 (D9) for bar 6


When you are happy with your changes experiment a little if you want and also try the chord substitute with the CTB Blues Bop videos in other Keys in the Jam-Room


Remember Always Revise

Have fun
