Please watch video above for in depth analysis:
Today we will look at applying the simple half step chromatic scale to jazz improvisation. This in turn will be reflected in the alternate picking guitar technique:
So, we will look at two parts,
1] Harmonic Aspect-Set-UP-Theory
2] Technical Execution-Set-Up-Instrument
The analysis will be detailed through this 2 5 1
MUSIC THEORY: Chromatic Scale:
If we look at the first bar we will see 4 note groupings “Tetrachords”. These groupings are made of semitones [chromatic scale].
What you will notice is that they “Outline” the Chord DmMaj7. This makes the ear follow the direction of the line in relation to the harmony so that it is not just aimless semitones strung together, but a connected line with a definite direction that resolves into an arpeggio.
These chromatic semitones in groups of 4 are “Even” Patterns and hence easy to alternate pick as the are all the same “Down Up Down Up”.
In the next bar we see the same technique: The chord is outlined again with 4 note chromatic scale groupings.
Finally we come to the last bar. This time we employ outlining by moving the chromatic scale up in minor 3rds [Diminished 7th].
In order to execute this type of playing it is essential to accent the 1st and the 3rd notes of each 4 note grouping. This will create a fluid rhythmic sound and hold the tempo tight.
If you watch the video at the top of the page you will see how the fretting hand works:
Here is the fretting technique that I employ in the video that sync’s the left hand with the right hand alternate picking:
I use GRIP, PLAY
RELEASE, MOVE HAND
RELEASE, MOVE HAND etc.
