Its three four-bar lines answer one another: four bars on I with a quick change to IV in bar 2, two on IV and two back on I, then V, IV and I with V in the last bar to turn it around. Dominant 7ths on every chord, the tonic included, are what make it sound like the blues. Practice the blues scale over the whole form, then learn to hear each change and follow it with the chord’s 3rd and 7th.
