The relative Major key starts a minor third (third containing 3 half steps
How to find the relative Major key from a minor key?
Tonic (first degree of the scale) of the relative Major key is a minor third above the tonic of his relative minor key. Don't forget that a minor third is contains 3 half steps
Examples, how to find the relative Major key from a minor key?
Finding the relative Major of G minor key
Here we will try to find the relative minor key of G minor key:
Tonic of the relative Major key is a minor third above the tonic of G minor key.
* Tonic of G minor key is : G
* a minor third added to G is: B flat
-> so the relative Major key of G minor key is B flat Major key
Finding the relative minor key of F minor key
Here we will try to find the relative Major key of F minor key:
Tonic of the relative Major key is a minor third above the tonic of F minor key.
* Tonic of F minor is : F
* a minor third added to F is: A flat
-> so the relative Major key of F minor key is A flat Major scale
