Minor blues is so much more expressive than the major one. It has more tension and pathos and it is ideal in order to compose intense melodic excerpts.
So as in major blues, it improvises on these structures just using chordal notes (the 1st ; the 3rd ; the 5th ; the 7th of the chord) and paying attention in varying the beginning and the end of the phrases (in different points in a-bar).
Minor blues structure and mood
This blues structure is one of my favorite harmonic forms. It is very expressive and music becomes consequently deep.
Thousands famous songs are based on these chords. These are different chords sub substitutions being more complex in jazz standards but which tend to simplicity just with three chords in rock-blues, funky, dance music and pop. I love simplicity and I prefer few chords, so that I can concentrate better on melody and phrasing creativity in playing. Remember modal music is often based on very few chords (“So What” by Miles Davis has two ones only).
