In this video I’ll show you how to build the harmonized scale, which is vital to find out what chord belong to a specific key. In the example I am building the Harmonized scale in the key of C major. In one of the successive videos of this series you’ll see that you can use these chords to build a very simple songs in a single key.
The process is fairy simple: I stack on top of every note of the scale two consecutive diatonic 3rds. Let’s say, for example if I start from C, the two notes will be E and G. If I start from D the notes will be F and A…is this easy enough?
In the example below every note of a major scale identifies a ‘grade’ of the scale. In the example I have used C major, but this is valid for every other major scale.
If I stack on every grade two more notes a third apart (basically every other one) I end up with different kinds of triads (triad=group of three notes). These triads are shown in the example below. If we analyze the intervals between notes:
On the guitar, like in the video:
You will have the same series of chords in all the other keys Eg: F major: F, Gm, Am, Bb, C, Dm, Em.
This again is valid for all the 12 keys. This concept is vital to understand how songs are built and how to pick the correct scale for a solo.
