Explanations
Chords and structure - This blues jam track in in 4/4 time is structured as a 12-bar song, by far the most common song structure in blues. It also uses one of the most standard chord progressions including the I chord on the first four bars. The chords are played in a progression as seen below:

Each bar last for two seconds. The complete structure is played four times (notice that in the last repeat, the D7 turnaround in the 12th bar is replaced with a G chord). The more you jam over 12-bar blues jam tracks with I, IV and V chords, the more you train your ear to hear the chord changes.
