This selection is a minor blues. Explain what this means. How is this different from all of the other blues selections presented in this chapter?

What will be an ideal response?

•All the other examples in the chapter have been in major keys where the important chords (I, IV, V) have a major third—a musical interval/distance of two whole steps--between their first and second chord tones[1]. For example, a major chord built on C is made up of the tones C E G (C to E is a major third). However, in "Ain't Enough Comin' In," which is a minor blues, the important i, iv and v chords of the piece are minor chords built with lowered (flatted) or minor thirds—a musical interval/distance of one and half whole steps--between their first and second tones. Using minor chords gives the music an entirely different quality from songs using the major I, IV, and V chords. For example, a minor chord on C contains the tones C Eb G (C to Eb is a minor third). Play these two chords—C major (C E G) and C minor (C Eb G)—on any keyboard and you will immediately recognize them and their distinctly different chord qualities.
