Hi Guys,
Following on from our previous lesson, we will now exploit the diminished 7th chord from our harmonised diminished scale examples.
To recap, here, is our basic shape:

PART 1 Harmonising a Simple Melody
To begin with, let’s take a very basic fragment of melody:

Now, we will simply harmonise this with our diminished 7th shape:

Notice, that straight away we have a sophisticated harmonic Palate and accompanying chord melody.
Let’s now stretch this further and broaden out on our diminished 7th chord shape by adding a couple of extra melodic notes:

From here, we will now harmonise the same piece of melody with slash chords from our previous lesson/video [on harmonising the diminished scale]:

Lastly, here are two examples with diminished 7th chords from the 5th and 6th strings. Both harmonising perfect cadences.
From 5th string

From 6th string

Examples from Standards:
Below, we have an example from “Stella” where we have both the minor7b5 and the diminished 7th [also Dominant7th].

In the next example, we have lots of colourful diminished 7th movement from the Gershwin classic “Someone to watch over me”.

Here, is the same but with the original Ab13 chord

Ascending Melody Harmonisation
To conclude, we will harmonise a simple ascending melody and add passing diminished 7th chords and vary it:

IN CONCLUSION
This was just a quick look at how to exploit melodies with the diminished 7th shape from our lesson on harmonising the diminished scale.
What you will notice, is how easily we can apply them as passing chords and colourful harmonic decorations to create really sophisticated accompaniments and chord melody functions.
For a really in depth take on this, it is a good idea to take a look at some Barry Harris material as this contains a huge wealth of possibilities. Also, for guitarists, Pat Martino’s approach to chords.
