Watch the Finding the Major Scale Shapes in Another Key online guitar lesson by Rob Garland from Melodic Soloing: Major Scale
In this video, I'll explain how to find the five shapes in other keys using the example key of A major. We're not using open strings, trying to find the lowest interval that a shape can be played from.
In this key, it would be F#, which is the 6th note of the key of A, so begin with Shape 6 on the 2nd fret, low E string.
Once again, remember the 6th note of a major key is always the relative minor, so if you wanted to play in the key of F#m, it’s the exact same notes as A major.
