This section will help you better understand transposition (changing
the key of a song or melody)
So if you learn a song in say the key of C major, you'll
be able to transpose it to another key,
for example to the key of G major or D major.
Why is it important? Scroll on.......!
First of all.... the most
important keys and their chords to learn as a guitarist are:
C major, G major, D major, A major, E
major.
They are often referred to as the "guitaristic" keys.
Thousands of songs are written for guitar in these keys.
Each key contains 7 basic triad chords.
So the key of A major has the following chords:
A Bm C#m
D E
F#m G#dim A
I IIm IIIm
IV V
IVm VIIdim

We'll change a simple chord progression in A
major to the same progression in C major.
They will "sound" the same but be in another key - C major.
A song in A major that used the following chord progression:
A / / / C#m / / / D / / / E / / /
using Roman numerals would be shown:
I / / / IIIm / / / IV / / / V / / /
The key of C major has the following chords:
C Dm Em
F G
Am Bdim C
I IIm IIIm
IV V VI
VIIdim
So the new progression in C major would be:
I / / / IIIm / / / IV / / / V / / /
C / / / Em / / / F / / / G / / /
