What Is the Bruce Protocol?

Blues (also translated blues) refers to a musical style. Blues music is also called blues, which is one of the recognized roots of contemporary pop music. It is actually a black American folk music style that had taken shape long before the Civil War. Black slaves created unique scales and harmony for it, and used it to send out a miserable life and pin homesickness. This makes the blues Music has a strong resentment from the beginning, so it is also known as a "complaint", a symbol of depression.

Blues music

Bruce (also translated blues) is based on five tones

There are two types of blues scale arrangement: major blues and minor blues.

First look at the blues scale in major:

C major blues: CD bE EGAC interval arrangement: major second, minor second, minor second, minor third, major second, minor third

Blues in D major: DEF bG ABD

Blues in E major: E #FG bA B #CE

Blues in F major: FG bA ACDF

Blues in G major: GA bB BDEG

Blues in A major: ABC #CE bG A

Blues in B major: B #CD bE bG bA B

"Gong mode": Interval arrangement: major second, major second, minor third, major second, minor third

"Major Blues" interval arrangement: major second, minor second, minor second, minor third, major second, minor third

Conclusion: The order of major BLUES scales is very close to the "Gong mode" in the pentatonic mode. We can think of the major BLUES scale as adding the Blues Note between the second and third notes in the palace scale arrangement.

Look again at the blues scale in minor:

Blues in A minor: ACD bE EGA Interval arrangement: minor third, major second, minor second, minor second, minor third, major second

Blues in B minor: BDEF bG AB

Blues in C minor: C bE F bG G bB C (This is a very typical Blues scale, bE, bG, bB three blues element concentration)

Blues in D minor: DFG bA ACD

Blues in E minor: EGA bB BDE

Blues in F minor: F bA bB BC bE F

Blues in G minor: G bB C bD DFG

"Feather mode": Interval arrangement: minor third, major second, major second, minor third, major second

"Blues in Minor" Interval Arrangement: Minor Third, Major Second, Minor Second, Minor Second, Minor Third, Major Second

Conclusion: The order of minor BLUES scales is very close to the "feather mode" in the pentatonic mode. We can think of the Blues minor scale as the blues note in the middle of the third and fourth notes in the feathered scale arrangement.

Blues originated in Africa. Initially, it had no chords, but the musician continued to play a bass note while singing different blues scales around this note. After a period of time, the blues composer found that these notes could be combined Forms a blues-like chord.
The usual blues mode is to add seven degrees to each chord, just like the mixed Lydia mode, it sounds like a seventh chord product polished by some other chords.

List some commonly used blues harmony:

Example: I7 (C7 chord in C major)

I7-IV7 repeat

I7-bIII-IV repeat

Twelve bars impromptu blues fixed harmony routine
