The
Circle of 5ths
As you can see from the chart below, If
you can memorise the circle of 5ths, and the
relationships that every chord has with one and
other, it will be possible to learn any song you like just by
hearing it.
For example: A song in the key
of C with 3 chords, would normally use the I (root) chord
C, The IV
chord F, and the V chord G.
From
the diagram
below, you will see that the 'IV' chord G is one
behind the C chord, and the 'V' chord F is one in
front of the C chord.
The 'I', 'V',
and 'IV' chords are
most commonly used chords in songwriting.
Moving on, you can also see
from the chart above that there is other chords that can be
associated with the 'I' chord. These are the 'iim',
'iiim' and 'vi' chords.
In the case of a song in key of C these
chords would be:
'iim' = Dm. 2 places behind C
in the diagram.
'iiim' = Em. 4 places behind C in the
diagram.
'vim' = Am. 3 places behind C in the
diagram.
The note in front of the root
note is Major 'IV'
The note behind the root note is Major
'V'
And the notes in positions 2, 3 and 4
behind the root note are all minor.
For example: a song in the key
of A
The 'I' chord would be A.
The 'IV' chord would be E (one behind
the root chord)
The 'V' chord would be D (one
in front of the root chord)
The 'ii' chord would be Bm (two behind
the root chord)
The 'iii' chord would be Dbm (four
behind the root chord)
The 'vi' chord would be Gbm (three
behind the root chord)
Use the progression map below to work
out chord progressions.
The rules are: from the 'I'
chord you can change to any other chord, but after that you must follow
the arrows to the next chord in the progression.
Starting with the 'I' chord go
to 'ii' then 'V' then 'vi' then 'IV' and back to 'I'.
In the key of C this would be:
C—Dm—G—Am—F—C
The chords in lower case can
be minor or minor 7 chords.
I've included a chart below, allowing
you to experiment with the chord progressions in different keys.
