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:

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 April 19, 2026June 1, 2026 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.

Frank Zappa:Octave Displacement Composition/Improvisation Techniques

Posted on March 8, 2026June 1, 2026 by Modern Music Theory and Application

Frank Zappa Octave Displacement Composition/Improvisation Concepts

Please watch video above for detailed info:

Hi Guys,

Today, a quick look at the way Frank Zappa exploits octave displacement.

This, is a really useful compositional device especially when writing for a string quartet or stringed instruments.

EXAMPLE 1:

In this example we can see the use of the displaced octave [or Maj7th interval].

Musical notation showing a Frank Zappa transition between Maj7th chords, octave displacement with notes and annotations indicating 'O/D' and direction arrows. — Musical notation illustrating Frank Zappa’s octave displacement used in string instrument compositions.

With further analysis, we will notice the employment of the minor 3rd interval as a means of connection and predictive avoidance.

Musical notation displaying a Frank Zappa melody with highlighted minor third intervals, with annotations indicating their locations on the staff with octave displacement. — Musical notation illustrating frank Zappa minor 3rd intervals in a compositional example.

Although, this phrase/motif descends a minor 3rd it is actually, [quite cleverly] copied up a semitone:

FULL LINE:

Sheet music showing a Frank Zappa guitar piece in 4/4 time signature, including standard notation and tablature for performance with octave displacement. — Musical notation illustrating octave displacement for string instruments, highlighting the use of minor 3rd intervals.

EXAMPLE 2:

This example is the same as that found in Pat Martino’s 12 chromatic forms:

This amazing shape creates a really nice resonance/blend on the guitar. It’s also useful for various inversions and shifting positions around on the fingerboard.

Here, once again we see the exploitation of the minor 3rd interval to move and connect the shape.
