Скачать или смотреть Minor Scales - Natural, Harmonic, and Melodic

The natural minor! The harmonic minor! The melodic minor! Like, why do we even have them?

This lesson isn't too hard, but you'll need to know what intervals are (like whole step, half step, etc.) and you'll need to have a basic idea of what a scale is.

Here's a good start on intervals and basic note relationships:    • How Basic Chords Work - Music Theory Lesson 1  
Here's a basic intro to major and minor scales:    • Major and Minor Keys (Music Theory)  

These aren't strictly necessary, but can be helpful:

Turning scales into chords:    • How to Fit Chords Into a Key (Music Theory)  
Introduction to modes (why the minor scale comes from the major scale):    • How to Turn a Mode Into Music
