In a blues chord progression it is common to play the flatted (minor) seventh above the root of the chord in addition to the three tones/notes that make up the basic chord (for example, G7 = G B D + F, C7 = C E G + Bb, D7 = D F A + C). What is the typical progression of chords in a blues stanza in terms of tonic, subdominant, and dominant?
 
  What will be an ideal response?

Question 2

Give the complete structural definition of the blues as a song form (Worlds of Music, p. 215). Define the important terms in the definition.

Answer to Question 1

 The Blues Chord Progression is:
 Tonic (I chord, built on the first scale degree) for measures one through four
 Subdominant (IV chord, built on the fourth scale degree) for measures five through six
 Return to tonic (I chord) for measures seven through eight
 Dominant (V chord, built on the fifth scale degree) measure nine
 Subdominant (IV chord) measure ten
 Return to tonic (I chord) measure eleven
 Dominant (V chord) in measure twelve if the blues is going on to another stanza or to the I chord if the song is ending.

Answer to Question 2

 Textually, a blues is a series of rhymed three-line or quatrain-refrain stanzas, each sung more or less to the same tune. Blues tunes usually consist of twelve measure (bar) stanzas, use a blues scale (variable 3, 5, or 7 scale degrees that may be lowered at the discretion of the performer) and blues are rhythmically complex, at times using syncopation (misplaced accents which fall on normally unaccented beats or in between the regular beats of the music) and/or polyrhythms/meters (more than one rhythm or meter at the same time; for example, the singer and his/her accompaniment are often in contrasting rhythms and/or meters). The singer often has a raspy, improvised vocal quality.
