Here is a fun example of changing a melody into another key using the key relationships. The original melody is written in the key of G major. The second score creates its relative minor, lowering the third, sixth, and seventh notes of the scale by a half step. The next score actually uses the key signature of G minor instead of accidentals. The last score is written in the key of E minor, the relative minor, by keeping the key signature and starting on the sixth note from the original pitch (B to G). Play each and listen to how the key relationships work closely together.
