harmonic minor scale – Modern Music Theory Improvisation and Application

Guitarist John McLaughlin’s use of the Diminished Scale for Chords and Improvisation:

Hi Guys,

Today, a look at how jazz guitar legend John McLaughlin makes cool and original sounding jazz lines from the diminished scale when improvising.

PART 1: CHORDAL SUBSTITUTIONS:

First of all, let’s apply a couple of Dim7 substitutions for the Dom7b9 chord.

In the example below, for the E7b9 chord we will employ Ddim7, Fdim7 chords over an E bass for a V to i cadence.

EXAMPLE 1:

Notice that the top line resolves:

EXAMPLE 2: Shifting the diminished 7th shape up to resolve for V to i cadence

Once again, the top line has a smooth half step resolution:

CHORD APPLICATION PART 2:

This time, we will employ the Dom13b9 chord in a full ii V i cadence.

As, in our previous examples, acknowledge the descending chromatic movement– resolving in the top line.

PASSING CHORD:

This time, we will add a passing chord. This will be Eb7#9. This falls smoothly from the Em7 chord.

We will also add a little bit of bass movement.

Also, in this example, we have two 1/2 step resolutions in the top line.

Finally, we will exploit a Dom13#9 chord as part of the ii V I cadence. [Once again, notice the chromatic moment on the 1st string/top line as we ascend this time].

EXPLOITING THE SOLO LINE:

Another interesting concept that John employs, is to use the “Ultra Locrian” mode or the 7th mode of the harmonic minor scale when dealing with diminished chords.

Here is the scale/mode over an Adim7 chord.

AVOIDING THE DIMINISHED CLICHE!

What puts John in a league of his own, is his avoidance of the usual tired diminished cliches .

Here, is an excellent example where John sequences in minor thirds. This though is an original, fresh and highly unique way of approaching diminished harmony and hence breaks the chain of cliches.

These 4 note groupings of tetrachords work great for sequencing with quick alternate picking guitar technique. [Starting on a down stroke]

THE INTERVALS: Key to creative lines

Looking at our example more closely we can clearly see the manipulation of intervals within the diminished scale/harmony.

This is what sets the great improvisers apart.

In this disguised manner the ascent in minor 3rds has a fresh interest to the ear due to the creative use of these intervals.

EXAMPLE 2

Here, we have the same thing in a different key:

Once again, acknowledge the use of intervals and tetrachords for rapid ascending movement with the picking hand.

Full Line:

IN CONCLUSION

This was just a quick look at how John McLaughlin exploits the diminished scale in interesting and unique ways that work extremely well not only for jazz, but, also specifically for the guitar.

John’s sequencing by exploiting 4ths, 3rds, triads and semitones creates an inspirational path, because it demonstrates that fresh life can be brought out from the diminished scale. This in turn makes the worn out cliches very easy to avoid.

John McLaughlin Alternate Picking Guitar Secrets part 1

Hi Guys,

Today, a quick delve into what makes John McLaughlin’s alternate picking guitar style work so easily and fluidly.

Many, focus on the right hand technique, but, much of it comes from the way the fretting hand works.

So, let’s look at a couple of simple secrets to John’s approach and why it is so fluid and effective

#1 OPEN STRING APPLICATION:

In this example, we will create an effective line that is not tremolo picking on cliche shred scales but a continuous colourful and creative improvised line in a world music style.

Here is the full line. Starting on a “Down stroke”

john-mclaughlin-guitar-secrets-alternate-picking-fast

If we take this apart we will find a couple of reasons why this is fluid and very natural for the alternate picking guitar technique.

First of all notice: The arpeggio that starts the phrase. The last note of this 4 note tetrachord grouping is an open D string!

This open string gives the fretting hand a hundredth of a second to do absolutely nothing as it prepares for the next 4 note grouping to fret.

This gives us time to get into position and so we are NOT rushing about, and, we are in control

CROSSING THE STRING:

We will now employ the use of an open string once again, but, this time for “Crossing” the string:

This makes it easy to cross the string smoothly and connect to the next tetrachord.

From here we will extract a partial John McLaughlin scale/fingering by sliding it into position.

To end this line, we will descend with some simple scale starting on an “Up stroke”. Also, notice the simple 2 finger fingering for the fretting hand.

EXERCISE 2: SEXTUPLETS: 6 NOTE GROUPINGS:

In this exercise we will employ groupings of 6 notes. This is based upon an improvised acoustic jazz fusion line, like that of “Belo Herozonte:

This is played over a ii V7 I of Dm9 G7 CMaj9:

If we take this apart we will notice that we exploit a Bm arpeggio going to a B dim arpeggio that then goes to the 4th and 6th notes of D Dorian: This creates a nice colourful sound.

For the next 6 note hexatonic grouping we employ an E harmonic/melodic minor sound over the Dm9 chord: Notice the Major 3rd interval:

From here, we will “Slide” the fretting hand up to the next position: Notice the use of the Major 3rd interval once again, as this breaks up the monotonous scale sound and creates distance and melodicism.

Finally, we have simple 2 finger pentatonic descending scale application that finally rest on the note C for the CMaj9 chord.
