relative majors of any key (It's super easy)
In addition to the six relative chords and the one diminished chord for every key, there are also two other common chords that are related to the root or tonic chord of every key. The root/tonic chord being the key we are in. So if we are in the key of A, the root/tonic is A, if we are in the key of F# then the root/tonic is F# and if we are in the key of Bb the root/tonic is Bb and so on.
We will call the root/tonic, the Key center and we will call the two other common chords relative majors. It is also easy to find the two relative majors. We start at the key center and move 3 frets up for the first relative major and then we go back to the key center and move 2 frets down for the second relative major.
See three examples below and the video lesson
Example 1; In the key of E the key center is E. 3 up from E is G, move back to the key center E and then 2 down from E is D. So the two relative majors for the key of E are G and D.
Example 2; In the key of F# the key center is F#. 3 up from F# is A, move back to the key center F# and then 2 down from F# is E. So the two relative majors for the key of F# are A and E.
Example 3; In the key of Bb the key center is Bb. 3 up from Bb is Db, move back to the key center Bb and then 2 down from Bb is Ab. So the two relative majors for the key of Bb are Db and Ab.
