Let us play the A and C natural minor scales with both hands on the keyboard. You simply start on the tonic and apply the pattern (W-H-W-W-H-W-W). Once you hear how a minor scale is supposed to sound, you will be able to play every natural minor scale by listening.
3. Key Relationships
You will notice that the C natural minor and C major scales are in a close relationship because they share the same tonic, C. The A minor scale also has a special relationship with the C major because they use the same seven diatonic pitches, which means they share the same key signature.
Relative keys are a pair of major and minor keys that share the same key signature. So, A minor is the relative minor of C major, and C major is the relative major of A minor. Parallel keys are a pair of major and minor keys that share the same tonic. C major is the parallel major of C minor, and C minor is the parallel minor of C major, so these two keys are in the parallel relationship. Let us exercise the scales in the relationships.
