Understanding Triads and Slash Chords in Music Theory

The 12 Major Triads/Slash chords music lesson in theory and practice:

Hi Guys,

Today, a look at altering harmony and cadences with triads, slash and altered chords.

To begin with let’s take a pedestrian V to I cadence,

Now, let’s add some colour to it.

Here, we can see the slash chord of Db/C resolving to C/F:

The Db/C harmony creates a powerful dominant chord of Csus/b9/b13

With this in mind let’s now apply this and cadence to the minor key [FmMaj7]

Straight away, we can see and hear how easy it is to manipulate and alter the harmony with slash chords.

They also possess a unique flavour and colour that really shines out on the guitar due to the Major triads being very bright. This way they naturally cut through and resonate.

In this example, we will take a simple triad of F Major 1st inversion [F/A]

From this, we will add melodic notes/movement in the top and bottom to extend the harmony, and, finish with a 7sus4 cadence of F/G to Cmaj7#11

Let’s now add this to a complete chord sequence:

We will now take the simple melody below,

To exploit this, we will employ altered and slash chords starting with G7#9 moving to Eb/E

We will now repeat this, but, add a chord of E/F in between to harmonise the Ab note:

Finally, resolving back to the Eb/E slash chord

In this exercise we will play all 12 Major Triads over a single C [as root] Bass note.

Jazz Guitar Alternate Picking Exercises: ii v7 I [Double Time]

Hi Guys,

Today, we will look at some alternate picking guitar technique exercises for jazz improvisation when double timing

We will exploit ii V7 I’s as a basis for honing our alternate picking skills whilst employing 4 note tetrachord groupings.

In the first exercise it’s a good idea to accent the third note in each four note grouping. We are also starting on a downstroke:

Here is the same exercise but with a variation in the second bar:

jazz-guitar-alternate-picking-lesson-exercies

The next exercise will employ groups of 6 notes called sextuplets: As an exercise we will start with an “Upstroke” this time. This will be played over an AmMaj7 pad:

2nd Part:

The following exercise uses some chromatic movement that smoothly connects to pentatonic movement starting on a downstroke:

In our final exercise we will join together some of these principles.

This was just a brief look at how to create alternate picking guitar exercises for improvisation through chord changes by applying simple patterns/fingerings that work naturally.

This was only around 140 bpm. But, this is essential before moving onto much quicker tempos with the alternate picking guitar technique.

With the 4 note “Tetrachord” groupings you will get fluidity through the changes. They will give you stability. They can then be broken up to create anticipation and syncopation-which will in turn create the natural expression of musical phrasing.

A Natural Minor Scale/Arpeggio:Basics

Hi Guys,

Today a quick look at the Chords,Scale and Arpeggios of the A natural minor scale.

To begin with this scale is exactly the same as the C Major scale but starting on the 6th degree:

c-major-chords-of-scale-diagram

a-minor-natural-chords-of-scale-diagram

Next we will play through and exploit and “Colour” the arpeggios of the scale:

c-major-arpeggio-diagram

d-minor-arpeggio-diagram

e-minor-arpeggio-diagram

f-major-arpeggio-diagram

g-major-arpeggio-diagram

We will now descend in broken chords in groups of 4 notes.

Here are a few examples of playing a different arpeggio over a different chord of the scale:

arpeggios-c-major-scale-superimpositions

Here is a basic way of breaking up the scale by employing triplets:

First we will do this on one string:

a-minor-scale-triplets-example

Now we will cross all 6 strings:

a-minor-scale-triplets-example

This time we will employ 16th’s in 4 note groupings of “Tetrachords” creating a double time smooth pentatonic line.

tetrachords-a-natural-minor-scale-example-pentatonic

We can change the Dominant [minor] chord in the A natural minor scale and make it Major:

With this in mind we realise that the G natural is now a G# and so we can employ the A Harmonic minor scale to play over it.

Here is a simple 2 finger fingering:

a-harmonic-minor-scale-dominat-chord-example

Now, let’s extend this:

a-harmonic-minor-scale-dominat-chord-example

We could also use the E7 Arpeggio:

e7-dominant-arpeggios-example

Finally, we have a lick with an arpeggio [that also implies a triad pair] going to a pentatonic phrase:
