Typically a 12 bar blues has the following chord structure: the tonic (I) is played for the first 4 bars, (16 beats), the sub-dominant (VI) plays the next 2 bars, the tonic again for the next 2 bars, then dominant (V) one bar, then sub-dominant one bar, and tonic (I) one bar and the last bar is usually the dominant or can be a tonic.
The tempo can very from slow to fast (60 beats per minute to 140 beats per minute).
This construct is 12 measures or bars at 4 beats each. For example in American Blues music, the 12 bar blues is used very often.
