How to Easily Harmonise the Diminished Scale Lesson

Hi Guys,

Today, a quick look at an easy way to harmonise the diminished scale.

PART 1: The Diminished 7th Chord

To begin our study, let’s take the diminished scale and play it on the 1st [E] string of the guitar.

Notice, the half steps and whole steps of the scale.

This scale can now be harmonised with diminished seventh chords.

What’s equally amazing is that with this form we have a separate diminished scale starting on each note of the chord itself.

This in turn gives us four part harmony.

The other interesting point, is that the first two chords of the scale incorporate all 8 notes of the scale:

So, now let’s harmonise the scale fully with the diminished 7th chord shape ascending:

The key from here, is to accentuate an inner or outer voice.

In this case we will accentuate the Soprano [or top line] scale ascending:

To continue our investigation, we will now accentuate the scale in the Bass.

Now, as we look at the chord and scale within the S. A. T. B. we can see the full realm at our fingertips.

The ascending scale of each voice is in full view:

PART 2: SLASH CHORDS

Another useful device for harmonising the diminished scale is to employ the use of slash chords:

These, will be moving in minor 3rds with the scale on the top.

Below, we have a triad of F Major played over a Gb bass. This is then followed by a D Major triad played over an Eb Bass.

These chords, are now sequenced: Moving up in minor thirds whilst carrying the scale on top.

In the next example, we will use another diminished favourite:

The minor7b5: Or Half diminished:

We, will follow this with our B/C slash chord form our lesson a little while back:

Now, let’s view the full chord scale:

Be amazed!…..Yes, this works out in all 4 parts once again:

PART: minor 3rd Chord Movement

To complete this, here are the two most common chord movements in minor 3rds for our scale.

This is NOT harmonised, but still essential to look at as it really displays the minor 3rd movement in both major and minor tonality within this scale.

Minor 7ths moving in minor 3rds:

Dominant 7ths with sharpened 9ths moving up in minor 3rds:

CONCLUSION:

This was just a quick look at how to harmonise the diminished scale.

These concepts are quite basic in many regards but contain a wealth of power for both on the spot Re-harmonisation and 4 part voicing for composition.

Traditional harmony and as we can see in this blog/lesson contemporary harmony both work well for the task.

Mastering Slash Chords: The B/C Explained

Posted on by Modern Music Theory and Application
B/C GUITAR SLASH CHORDS GUITAR LESSON AND EXAMPLES

Please watch video above for detailed info:

Hi guys,

Today, a quick look at the idea of employing slash chords.

To do this we will focus on one specific chord that of B/C.

CHORD VOICING:

In the notation/tablature below, notice the use of a B Major triad over a C bass:

Here, are a few more voicing’s:

1]

2]

3]

4]

SOLO LINE EXAMPLES:

This chord works well with the diminished scale. But, in order to come up with something unique we are going to take a different approach.

Because, we have the B Major chord we can exploit Pat Martino’s minor conversion technique.

In this case, we will employ the minor a Major 3rd up. This will be D#/Eb as the minor key:

IDEA 1:

Here, we will employ the simple Eb minor arpeggio:

IDEA 2:

This time, we will employ scale movement inside of the Eb minor arpeggio shape in a horizontal form.

IDEA 3:

Let’s do the same, but, play with the notation and give it a diminished flavour:

IDEA 4:

Now, let’s take a B Major arpeggio and ascend it by making sure our C bass note is within it.

NOTE: There are also two open string notes of D natural [minor 3rd] and the open E. I used these as they make the arpeggio flow easily when alternate picking.

IDEA 5:

We can also add some chromaticism for smooth movement.

COMPOSITION- APPLICATION IN CADENCE

Finally, let’s see how composition can be exploited with our slash chord.

To do this, we will create a ii V7 I cadence:

NOTICE: In the example above, we can see that the minor becomes diminished and the Dominant becomes 13b9 and the I chord becomes our slash chord that resolves yet hangs in the air.

Master the Whole Tone Scale with Simple Fingering

Posted on by Modern Music Theory and Application

Please watch video above for detailed info:

Hi Guys,

If there are two scales that I am always asked about, these are the whole tone scale and the diminished scale.

But, out of the two, it’s the whole tone scale especially!…And it’s due to the general textbook cumbersome and awkward fingering that puts guitarists off.

So, today let’s take a look at how to play the Whole Tone Scale with a simple fingering like that which we would employ for the pentatonic scale.

PART 1:

Standard textbook guitar fingering:

This, 3 note per string example above is a pretty uncomfortable and awkward affair that dosen’t flow and isn’t especially fluent for quick passages or phrases.

So what do we do?

Well, the answer is to approach it like we would the pentatonic scale, so that we can move the SHAPE about and at the same time we can VISUALISE it.

PART 2:

Here, is a preferred fingering that uses mainly 2 fingers: This, like the pentatonic means that we can move about quickly.

What’s truly great about this fingering is that we can copy and repeat it exactly “Down 1 Tone or Up 1 Tone” each time right along the guitar fingerboard.

BASIC SCALE SHAPE/FINGERING;

Copy Shape Exactly Ascending:

Copy Shape Exactly Descending:

Copy Shape Exactly Ascending:

This means that we can easily exploit the scale, play it fluently and see it visually which in turn gives us complete command of it.

PART 3:

Now, that we can see and hear what we are doing and have a fluent fingering let’s make use of the scale harmonically.

To begin with, let’s use a flattened 5th interval [and Bb7] over a moving bass. [See video at the top of the page].

Now, let’s use this same harmony and create an [arpeggiated] chordal picking vamp:

Sheet music and guitar tablature showing a repeating whole tone scale triplet pattern with flat notes and finger positions on the 5th, 7th, 9th, and 10th frets

Again, it’s easy to see and hear how we can quickly create composition now that we can visualise a simple shape all across the guitar fingerboard.

PART 4:

What, also works really well from this visual whole tone approach is the exploitation of the high low high [or mirroring] effect.

EXAMPLE 1: High to Low

Sheet music with treble clef and tablature showing whole tone scale musical notes and finger positions on a guitar fretboard

Here, we will create a little phrase that’s going back and forth between the low and high registers.

EXAMPLE 2: Back and Forth

PART 5:

We will now apply this simple scale fingering to a classic Messiaen chord

Application and example:

Sheet music and guitar tablature for a Messiaen piece in Gb9b5/E chord showing notes and finger positions

PART 6:

Finally, we can come out of the shape and move up and down the fingerboard connecting the whole tone [1 step] movements.

So, let’s take a chord of C augmented with a 9th:

As we can see, it’s easy to move down the fingerboard shifting through scale and arpeggio along the way. [See, video above]

IN CONCLUSION:

This was just a quick look at how essential it is to have simple fluid guitar fingering and simple 1 step connection for creating whole tone scale lines/phrases.

Having a “Visual” as well as harmonic understanding makes improvisation and composition so much easier with this scale.

And, as I have reiterated throughout this post, having a repeated shape only 1 tone apart makes the scale very user-friendly.
