Today we’re going to look at some ‘Tritone Substitutions’. So what is a Tritone and what is a Substitution?

Understanding the differences between the scales and modes can feel like a daunting task. What makes a scale Major or Minor? Why do we get different chords from different scales? Understanding the intervals which make up each scale or mode can help. One way to do this is to learn the scales across a single string so that you can more easily see the distances between notes.
In this post we’re going to look at 11 different scales/modes, all starting from the root note A. We’ll play these single string scales on the A string to keep things simple. Moving these patterns to other strings will give you different key centers as will moving the patterns up the fretboard. We’ll start by looking at all twelve intervals in relation to the note A:

Today we’re going to look at the ‘Circle of Fifths’. You may have come across the term before, or the ‘Circle of Fourths’, or just ‘The Circle’.
Check out the diagram below and then we’ll look at what it means and why its useful.
As you can see if we move clockwise in The Circle of Fifths we go up in fifths, e.g. C to G. If we move anti-clockwise we go up in fourths, e.g. C to F. The inner ring shows the relative minor key of each Major key. For example the relative minor to C Maj is Am. The relative minor of G Maj is Em etc.

Welcome to part 2 of our exploration of seventh chords. In part 1 we looked at the more common types of sevenths, in this part we’re going to look at some which you won’t come across as often.
You can get some quite unusual sounds from some these chords because of their altered extensions. Remember these chords will be derived from a particular scale or mode and some of these chords are exclusive to their mode.

Today we’re going to look at extending the basic chord triads by adding a 7th. This will give us a whole new set of ‘Seventh Chords’.
If you’re not sure how to form the basic triads check out our post on doing exactly that, here. You may also want to check out our post on intervals if you’re not sure of the difference between a minor 7 and a major 7, however the diagrams below should make things fairly clear.

In this episode we’re going to learn how to harmonize the major scale to form diatonic chords. ‘Diatonic’ chords are chords which have been created using the notes from the major scale.
If we make a basic chord triad from each degree of the scale, we end up with seven chords. A chord triad is a group of three notes, usually a root, third and fifth. These are are all degrees of the major scale.
In this episode we’re going to take a detailed look at intervals, what they are and how to use them effectively in your playing.
Essentially intervals are simply the distance between notes, however with a little understanding you can harness the true power of intervals to achieve any sound you want. We’ll also learn about interval note relationship and how this can help unlock songwriting creativity.
In music Roman Numerals are used to denote the scale degrees and which degree a chord is built from, for example the V chord is the chord built from the fifth note of they key (In C major this would be the note G).

In this series of lessons we will look at the modes of the Major Scale. We’ll learn how the modes relate to the major scale and look at when and how to use them.
Modes seem to be a source of confusion for a lot of people, especially the ‘self-taught’ guitarists among us. You’ll also often see modes of the major scale listed in books for reference but with little or no explanation of how to use them.
So what are the modes of the major scale?
A mode is basically the major scale, shifted along so that the ‘root’ note is different, for example in C major the second note is D. The second mode of the major scale is ‘Dorian’ so in C major we get the D Dorian mode. The notes of D Dorian are the same as C major except they run from D to C instead of C to B.
Let’s start by looking at the Major Scale itself:

Dorian is the second mode of the major scale so we get it by starting from the second note instead of the first. In the Key of C major the Dorian mode would be D Dorian, the notes would be D-E-F-G-A-B-C-D. The same notes as C major but starting from D instead of C.
The Dorian mode is normally used over a m7 chord, this is because the II chord in a major key is a m7. See our post on building chords from the major scale for more information. So if we have a chord progression which contains a II chord we can use the Dorian mode to solo or write a melody over it. We can also write chord progressions which resolve to Dorians I chord. For example dm7.
