3.1Start with the easiest minor scale: A minor

A natural minor:

A B C D E F G A

= ля си до ре ми фа соль ля

Notice something important:

It uses exactly the same notes as C major.

C major:

C D E F G A B C

A minor:

A B C D E F G A

Same seven notes.

Different home note.

This relationship is called relative major/minor.

So:

C major ↔ A minor

They share the same key signature: no sharps or flats.
