How can I change a musical composition from a major key to a minor key, specifically from A flat major to A flat minor?

To change a musical composition from a major key to a minor key, specifically from A flat major to A flat minor, you would need to lower the third, sixth, and seventh notes of the scale by a half step. This means changing the C, F, and G notes to C flat, F flat, and G flat. This alteration will give the composition a minor key feel.
