What is the formula for the 12-bar blues?
In whatever key you are in, 12-bar blues uses the same basic sequence of I, IV, and V chords. It is most easily thought of as three 4-bar sections – the first 4, the middle 4, and the last 4 bars. The first 4 bars just use the I chord - I, I, I, I. The middle 4 bars go IV, IV, I, I.
How many beats does a 12-bar blues bar have?
The term "12-bar" refers to the number of measures, or musical bars, used to express the theme of a typical blues song. Nearly all blues music is played to a 4/4 time signature, which means that there are four beats in every measure or bar and each quarter note is equal to one beat.
