Minor Scale Melody
Add two notes to the minor pentatonic to complete the minor scale — a familiar, sweet and solemn sound, nearly as common as the major scale. As a mode of the major scale, it uses the same triads and pentatonics in a different order.
Why
The minor scale and its modes color everything darker; learn to hear each shade
Notice how emphasizing a different note within the same set changes the feeling entirely
Learn to rotate the structure of the major scale to play its other modes
