Intermediate Chordacus

See the entire fretboard with Chordacus!

Chordacus is a software tool that you can use to find chords, scales and arpeggios in different keys on the guitar.

All these images have the same colour co-ordination system in order for you to learn and remember the shapes as easily as possible.

In the Intermediate Guitar Course you learn all your barre chords, this is when Chordacus starts to become useful as you can move all the barre chords to different keys and shapes.

We also start studying the minor and major pentatonic scales, when you learn these you will still see the chord shape inside the scale shape.

Minor Pentatonic in Chordacus

Lets start with looking at the Em barre chord shape, and how it is developed into a Em shaped Minor Pentatonic.

Chord notes (Root, minor 3rd, 5th) -red

Notes from the minor pentatonic around the chord -blue.

Below is a C minor pentatonic scale, in an Em shape.

Major Pentatonic in Chordacus

In major we get a major pentatonic around the chord shape, the notes are now yellow.

Chord notes (Root, minor 3rd, 5th) -red.
Notes from the major pentatonic around the chord (2nd, 6th) -yellow.

On string 5, the major third is yellow since it is not part of the chord shape.

Displayed here is a C major pentatonic, E shape.
