Re: Forget Modes - Advice That Set Me Free

My problem before was like this. In the Am pentatonic,
A Blues, and then playing an A7 (A,C#,E,G but since I'm talking blues I should say A,Db,E,G) there's no C#/Db unless you add in a natural 3. Which I have since learned is acceptable. The blues is free and accepting of additional notes as needed.
Good! I hope you realize by now that the A min pentatonic played over an A7 in an "A" blues does not indicate the key of the song is any different that what it started out to be. That happens to be A major.
Think of it like this. Suppose a song is in A major and a tone deaf singer gets up to the microphone and sings a bunch of wrong notes. That doesn't change they key of the song or modify the original chord progression does it? No! All it means is that the singer is simply in the wrong key (which, by the way, has nothing to do with theory). :laugh2:
Blues is sorta like that If you view it purely from the standpoint of classical music theory. By chosing an A min pentatonic you have created a controlled situation where you are purposely playing in the wrong key from the standpoint of classical theory.
So you must ask yourself this question: "When a poor black guy came home after a hard day's work in the late 1800's to early 20th century and picked up an old rusty guitar to play some blues he had ..."
A. been pickin cotton all day.
B. been studying Mozart.
Also please consider that the physics of Sir Isaac Newton is great for predicting where a ball shot from a canon might be expected to land. Once you delve into the world of subatomic particles however, Newtonian physics fails to make accurate predictions. That's why physicists developed Quantum Mechanics. It would be rediculous to try to apply Newtonian physics in an attempt to predict the behavior of gluons, neutrinos and quarks!
Likewise the theory that you have been studying was great for Mozart when everything was based on purely diatonic constructs and harmonies that never extentended beyond the first octave. That theory has since been updated so that it could more accurately describe musics from later periods in history that defy the original classical theory. The theory that describes Brahms, Wagner, Debussy and Copeland had to be updated from the original classical theory. In short there is an up-to-date music theory that accurately describes styles like blues and jazz that you haven't touched on yet.
Complete the theory that you are studying now, but use it for what it is ment to be used for. That is the study of musics that are obedient to the polite diatonic world of classical music and its basic concepts. Once you have a firm grasp on this "classical" theory then advance forward to modern music theory. It is there that you will find the explanation for styles like blues and jazz that you seek.
