Hi all,
It occurred to me that in the 8-bar and 16-bar blues threads, we have always thus far tied the forms to chord progressions, which can be helpful, but which altogether neglects the extent to which the vocal phrasing and phrase lengths are what really drive blues phrasing. Bearing that in mind, I thought it might be helpful in understanding the different blues forms to see how the vocal phrasing tends to be expressed in each form type.
A 12-bar blues is most often expressed vocally in 3 four-bar phrases. In some of the earlier country blues, the same lyric may be sung 3 times, as in Henry Thomas's "Bull Doze Blues I'm
going where you never get bull dozed I'm
| I | I | I | I |
going where you never get bull dozed I'm
| IV | IV | I | I |
going where you never get bull dozed
| V7 | V7 | I | I |
In this instance you can see that Henry Thomas was phrasing in front of the beat, and was starting each vocal phrase in advance of the downbeat of the 4-bar phrase. In this case, and in many or most others, the same melodic line is sung over the first two 4-bar phrases, and the way it sounds different over the IV chord in the second phrase as compared to the I chord in the first phrase is what creates much of the tension in the blues sound. The melody in the third phrase, or tag line, is usually different, and creates a resolution to the tension between the first two lines. Note, too, that most of the singing occurs in the first two bars of each four-bar phrase; this leaves the second two bars of each phrase available for an instrumental response or fill.
A more commonly encountered vocal phrasing for a 12-bar blues involves the introduction of a vocal line in the first 4-bar phrase, which is then repeated in the second four-bar phrase, followed by a tagline in the final 4-bar phrase that comments on/resolves the earlier repeated line. From Mance Lipscomb's "If I Miss The Train":
If I mi-
ss the train got a big black mule to ride If I mi-
| I | I | I | I |
ss the train got a big black mule to ride If i mi-
| IV | I | I | I |
ss that mule got a automobile to drive
| V7 | I | I | I |
The vocal phrasing here is very similar to that in the Henry Thomas song, the biggest difference being the presence of the different tag line. The harmony is slightly different, with the I chord returning in the 10th bar rather than the 11th. These subtle changes in the blues form tend to be more commonly encountered in Country Blues than in modern day amplified blues.
Another kind of 12-bar vocal phrasing which became really popular in the 1930s is what I would call the "Chorus Blues". For some reason, it has always had a more Show Biz or Pop feel to it for me than the previously discussed 12-bar phrasings. In the Chorus Blues, a different line is sung over each of the first four bars of the form and then the chorus arrives as you hit the IV chord, continuing to the end of the form. The Mississippi Sheiks' "Sales Tax" is a good example.
Old Aunt Martha lives behind the jail A sign on her door says "Liquor for sale"Oh the
| I | I | I | I |
sales tax is on it Oh the sales tax is on it yes the
| IV | IV | I | I |
sales tax is on it everywhere you go.
| V7 | IV | I | I |
Other well-known Chorus Blues include Tampa Red and Georgia Tom's "Tight Like That" and Memphis Minnie and Kansas Joe's "Bothering That Thing". Note that in the chorus blues, the only lines which change from one verse to the next are those that are sung over the first four bars. Also, the lyric-heavy nature of the first four bars does not really allow any space for fills. The fills tend to fall in the 6th, 8th, 11th and 12th bars.
8-bar blues phrase out differently than 12-bar blues, as you might expect. Though not so commonly encountered, there are 8-bar blues that simply sing the same line twice (though with a different melody in the repetition). John Hurt's "Slidin' Delta" goes
That sli---din' del--ta run right by my door
| I | V7 | IV7 | IV7 |
slidin' delta run right by my door
| I | Vmin7 | I | I |
Often an 8-bar blues will phrase out vocally as one longish thought with no repetition a la Furry Lewis's "Dryland Blues"
I can look through muddy wa-ter, baby, and spy dryland If you
| I | V7 | IV7 | IV7 |
don't want me, baby, let's shake hand in hand.
| I | V7 | I | I |
From these examples, you can see that the biggest space for fills in the 8-bar form falls in the 7th and 8th bars, and it is no coincidence that Furry and John Hurt both often extend the form between verses by really loading on some great fills.
As with the 12-bar form, the 8-bar form similarly has its own version of the chorus blues. Two of the archetypal 8-bar chorus blues are the Mississippi Sheiks "Sitting on Top of The World" and Leroy Carr's "How Long Blues"
How long, how long, has that evening train been gone? How lo-
| I | I7 | IV7 | IV7 |
-ng? how long, baby how long
| I | V7 | I | V7 |
Leroy Carr created such a beautiful rhythmic tension in this song in the placement of his vocal phrases relative to the pulse and chord changes. Notice how nothing squares up and he is constantly phrasing across bar lines and chord changes. Genius! The 8-bar chorus blues creates a natural space for a turn-around in the 7th and 8th bars, the idea of the turn-around being a nifty series of chords which moves you from I to V7 to lead back into the next verse. Like the 12-bar version of the chorus blues, the only lyrics that change from one verse to the next in the 8-bar chorus blues are those that fall over the first 4 bars. I will talk about the 16-bar blues next.
All best,
