/*
The western scale is commonly found in 'western pop' music.
It consists of 12 notes that are 1 intervals apart to form an octave.
Eg. C, C#, D, Eb, E, F, F#, G, G#, A, Bb, C
Other notable scales such as the Pentatonic scale which consists of only 5 notes and
the Indian scale which has 24 notes.
We need to normalize the notes available to our western scale into base notes because
the following pairs are equivalent.
C# = Db
D# = Eb
F# = Gb
G# = Ab
A# = Bb
It is just a matter of convention when we favoured C#, Eb, F#, G#, Bb over their
equivalents in rendering our base notes.

/*
In our CAGED system, we'll be using positions as defined in the following matrix
C = position 1
A = position 2
G = position 3
E = position 4
D = position 5
As such position 1 can also be called the 'C shape' position, position 2 the
'A shape' position, etc.
Playing different chord voicings then becomes nothing more than just shifting the
appropriate shapes around to coincide the shape's root note with the desired chord's
root note on the fretboard.
Eg.
Fret 0 X_R_______O
|_|_|_|_|_|
|_|_1_2_3_|
Fret 3 |_|_|_|_|_|
|_|_|_|_|_|
An 'A shaped' A major where its root note is at 'R'
Fret 0 X__________
|_|_|_|_|_|
|_R_|_|_|_1
Fret 3 |_|_|_|_|_|
|_|_2_3_4_|
An 'A shaped' B major with root of A shape over B note on 5th string
Position/shape can be defined in our chord token,
Eg. C:1, Cmaj7:3, etc.
where the numbers 1-5 after the ':' in token reflects the desired position/shape.
If in the absence of specified position/shape in token, we'll use the most playable
shape as the desired chord's position/shape. In general,
- Chords with root note within C, A, G, E, D will take the shape of it's root note except
* major 7ths
* minor chords
* dominants above 7ths, eg. C9, C11, etc.
* augmented chords
* diminished chords
- E & A shapes (good for barred chords) will be considered for exceptions above
- Chords with root note that falls within B, Bb, C#, Eb will use A shape
- Chords with root note that falls within F, F#, G# will take E shape
