4. Pitch Axis Theory Explained

Guitar modes explained in a different format.

We have included an explanation of the Pitch Axis Theory in this article and in the lesson page, mainly as a yard stick to indicate how much simpler the Guitarmodes method is compared to Pitch Axis Theory.
A huge number of dots would be necessary to cover the fretboard to get the information across to the student (we did not show the dots).

Firstly, You would need to be an experienced player with the ability to play the major scale in all keys across the fretboard. Then count frets from the root note to find a starting point for a mode. You would also need to start each mode with a diffent finger.
The Pitch Axis Theory is suitable for musicians who have previous knowledge of scales.

Guitarmodes will allow you to do all this and play across the entire fretboard with one simple concept in one simple lesson.

PAT:

Ionian
Play through 1 octave of the major scale.
In the key of E at the 12th fret, use an E major chord as backing, you will be in the Ionian mode.

Dorian
Move that same major pattern down 2 frets to the 10th fret.
In the Key of E, using an E minor chord, you will now be in Dorian mode.

Phrygian
Move that same major pattern down 2 frets to the 8th fret.
In the key of E, using an E minor chord, you will now be in Phrygian mode.

Lydian
Move that same major pattern down 1 fret to the 7th fret.
In the key of E, using an E major chord, you will now be in Lydian mode.

Mixolydian
Move the same major pattern down 2 frets to the 5th fret.
In the key of E, using an E major chord, you will now be in Mixolydian mode.

Aeolian
Move the same major pattern down 2 frets to the 3rd fret.
In the key of E, using an E minor chord, you will now be in Aeolian mode.

Locrian
Move the same major pattern down 2 frets to the 1st fret.
In the key of E, using the E diminished chord, or(minor chord) you will now be in the Locrian mode.

Then back to E.

Each time you play an E note anywhere on the fret board, it will become your starting note for your mode. E note will end up under a different finger for each mode.

A reference to locate a starting position for a mode would be to select a key eg. E, 12th fret.
Play a major scale pattern on 1 string going down the neck eg. 12th 10th 8th 7th 5th 3rd 1st frets.

Great hidden gems but a lot of work putting it all together.

Guitarmodes has found another hidden gem, going way beyond the outcome and nowhere near resembling the compexity of the Pitch Axis Theory.
