Theory and Conventions

A scale consists of eight notes (octave) When two or more notes of a scale are played simultaneously

then this represents playing a Chord based on the scale Each scale note is identified by its position in the scale The first note of a scale is called the root The root note played together with the third and fifth note of the

scale provides the Major Chord for a given scale A chord which only uses three notes of the scale is called a

Triad Other notes may be added to a chord in simple or complex

ways which will have an affect on the overall sound


The C Major Scale with Associated Notes

1 2 3 4 5 6

The first note of the scale is called a numerical Degree of the scale e.g first note is the First Degree, next note is theSecond Degree

7 8


The Chord of C Major C, E, G


The C Major Chord Triplet C F G C

The major chord based on the first of the scale is then

followed by the major chord based on the fourth note

of the scale followed by the major chord based

on the fifth note of the scale finishing on the first major chord

1 2 3 4 5 6 7 8


The Chord Sequence C Major, F Major, G Major, C Major

This sequence of chords forms a natural grouping that ‘sounds right’ musically.


The Chord of F Major F, A, C


The Chord of G Major G, B, D


The Chord Sequence G Major, C Major, D Major, G Major

The F in D Major is Sharpened as this follows the key signature for that scale


The Chord of D Major D, F , A


What is The F Major Chord Triplet ?

1 2 3 4 5 6

The major chord based on the first note of the scale is then

followed by the major chord based on the fourth note

of the scale followed by the major chord based

on the fifth note of the scale finishing on the first major chord

7 8


The Chord of B Major B , A, C


The Chord of C Major C, E, G with single bass note C


Minor Chords

A minor chord has a distinctive sound. Each major scale has an associatedRelative Minor Scale which is based on the Sixth Degree (Note) of the Major Scale
