What is 12 bar blues progression?

Many music fans were surprised to see a dozen musicians who improvised a blues song during the improvised Jam Hitting session. It seems that without much discussion or practice, all participants instinctively know when to change the chords and how to approach the song. In fact, however, these musicians knew all the time how their "improvised" song would sound- it is a standard musical form called 12 Bar Blues Progression. Musicians learn 12 bar blues progression, like dancers, learn basic time steps. This allows amateur musicians to play with more experienced professionals and know exactly what chords to play.

To understand how standard 12 bar blues progression works, it can be useful to explore three main elements- twenty bars, blues and progression. Almost all blues music is written in 4/4 times, which means that a quarter note will receive a full beat and four of these rhythms include measures. In notation notation, measures are marked with verticalStripes, so many musicians informally refer to measures like bars. The total length of 12 bar blues progression is twelve measures, although the procedure is generally repeated until the song ends. There are variants of 12 bar blues progression that use only 8 bars before repeating.

blues refers to the real style of the song. Blues Music has a unique rhythmic pattern that most musicians use to control their playing. Although the blues are written in 4/4, the real rhythm is rather symbolized backbeat. Instead of a standard two two four/two two four four regularities of most 4/4 compositions, blues music uses a driving rhythm: "Bom BOM BOM BOM BOM BOM/BOM/BOM BOM BOM BOM". This synchronized, control rhythm gives 12 bar blues progression of its lowering and earthy sound.

Progression

refers to changes in chords made during 12 bar blues riff. The blues song can be in any key, but musicians generally agree on the easiest guitarist keyboards, such as E or D. Once the overall key is intended, musicians follow the standard pattern when changing chords. The first four measures are in the tonic chord key- if the song is in the key D, the tonic chord is d main. Head singer sings a pitiful lyric about his life: "This morning he woke up/wind howl at my door." After the fourth measure, the band increases to a subordinate chord (in this case G Major) and the singer repeats this line with more urgent: "I said I woke up this moooorning/wind howling at my door." The band then returns to the original Tonic chord (D Major) and plays two more measures.

The last measures are played and sings differently. A new lyric is introduced by a singer who covers the original line: “I don't know if I can/can't eat itt floor. ” At the same time, the band moves to the dominant chord (Major) with the name of the seventh added. Finally, he returns to the original tonic (D Major).

Blues progression is harder to explain than to actually do them. When the singer begins with a new lyric, musicians play the dominant seventh chord for tension, a sub-dominant for some release of this tension and tonic to re-start the whole procedure.
