"Harmony rules" were the first efforts to talk harmony

In the "modal analysis" postings, focusing talked known melody can accurately determine the tuning, and draw tuning tone Price (seven sound). This tone is also known as seven seven "natural sounds." In C major scale, for example, seven natural sounds are: C, D, E, F, G, A, B, (C). Their corresponding natural chords are: C, Dm, Em, F, G, Am, Bdim, (C). For the "Harmony writing" both in terms of chord material. They have a name called the chord's "musical alphabet flag" is also called chord "fixed mark." There is a more common name is the chord's "tone-marking", with Ⅰ, Ⅱm, Ⅲm, Ⅳ, Ⅴ, Ⅵm, Ⅶ0 to represent the seven chords. The following discussion in this tag-based. Because different tuning their "fixed mark" different, but the "sound level mark" the same. G major scale of the "fixed marker" is: G, Am, Bm, C, D, Em, # Fdim. The "tone-marking" is still: Ⅰ, Ⅱm, Ⅲm, Ⅳ, Ⅴ, Ⅵm, Ⅶ0 to represent. Their names are: Main chord, the main chords, the chords, subordinate chords, chords, chords and lead the next chord. 
Distance relationship and affinity between these different chords sound level is different. "Affinity" is the driving force to promote harmony forward. Also known as "harmonic progression efforts." The intensity is a "vector", the "direction" but also "size." Understand the intensity of the "direction" and "size" is to understand the premise of the law of harmony. Nature has given mankind a "velocity" of quantitative units "chord (root) of pure five degrees downward." "Efforts," the direction is pointing to the "main chord." Press the "intensity" lists the chords: 
Bdim, Em, Am, Dm, G, C, F; 
Ⅶ0, Ⅲm, Ⅵm, Ⅱm, V, I, IV; 
reader is easy to see: seven natural chord is from left to right Press the "pure five degrees downward" arrangement. It is noteworthy to Ⅶ0 Ⅳ relationship is minus five degrees (Attention! After the discussion is a difficult). 
From grade Ⅰ (main chord) closer chords, acoustic intensity is stronger, the weaker the farther acoustic intensity. Ⅰ from the higher level (main chord) closer chord frequency of use. Ⅰ from practice, Ⅴ, Ⅳ (three positive triads) level sufficient to prove the use of the above conclusions. Digit number assigned to them for quantitative analysis. 
5 - 4 - 3 - 2 - 1 - 0 - (--1) 
Bdim- dm- G C Em Am-F; 
Ⅶ0- Ⅲm- Ⅵm- Ⅱm- V- I- IV; endowed with Ⅰ level 0 represents the origin of all power chords point level Ⅰ (main chord). Ⅳ negative 1, indicating Ⅰ level downstream pure five degrees. An interesting phenomenon appeared, Ⅴ- Ⅰ (1-0 = 1); Ⅶ0- Ⅲm (5-4 = 1); Ⅰ- Ⅳ (0 - (- 1) = + 1); •••. 

They are such a chord progressions are "Goldge conduct" or "Goldge termination." And Ⅳ-Ⅰ ((- 1) -0 = -1) is "declension" OR "declension termination." 
When readers learn "fingering" level will find harmony according to: Main Main chord chord ••• ••• main chord, as if the periodic emergence of the main chord (stable chord). The middle is a series of unstable chords. This "stable", "unstable" to return to the main chord change of the final overall harmony of the composition.Unstable chord harmonies determine the object of writing. 
Five degrees above the chord to chord downward is called "linear chord progression." Is the most basic chord progressions. There are also two subsequent introduction.
