There are three different types of minor scales:
a) Natural Minor Scale
b) Melodic Minor Scale
c) Harmonic Minor Scale
All three minor scales differ from the major scale by having a flattened third note. This is referred to as a minor third. This gives it its sad, minor sound. Let's look at the natural minor scale first.
The Step Pattern is as follows:
So, in the key of A minor (note, as in C major, there are no sharps or flats), we get:
On the guitar, we could play it on the G string (3rd string) like this:
Since it is not entirely functional to play a scale on a single string, we can find the notes of this scale across all strings, as outlined below.
This pattern can be used when the root note of the natural minor scale falls anywhere on the 5th string.
This pattern can be used when the root note of the natural minor scale falls anywhere on the 6th string.
