The term "blue" has described a condition of depression or melancholy
since at least the 16th century (New Grove); it apparently entered
the American vocabulary after the Civil War. In the 20th century can
to describe music that portrays such a state of mind. Performance or
interaction with the music can also be seen as a means of ridding oneself
of "the blues."
This aspect of the blues has traditionally been seen as an important
part of the performance of the blues - "many maintain one cannot play
the music unless one has ‘a blue feeling’ or ‘feels blue’."
Performance Style
"Many jazz players of all schools have held that a musician’s ability
to play blues expressively is a measure of his quality. Within blues
as folk music this ability is the essence of the art; a singer or performer
who does not express ‘blues’ feeling is not a ‘bluesman’."
Particular performance techniques include:
"rough" or "unrefined" timbres
"blue" notes such as the b3 or b5, or deviations from "standard"
pitch
improvisation, including variations of the melody and solos
Form
Although not all songs with "Blues" in the title follow this form,
a "standard" blues form evolved in the early 20th century.
The lyrics follow an AAB form in which the the first 2 lines are
the same (or very similar) and the third line contrasts in some way.
The New Grove offers the follwing example:
I’m troubled in mind, baby, feelin’ blue and sad.
I’m troubled in mind, baby, feelin’ blue and sad.
The blues ain’t nothin’ but a good man feelin’ bad.
Although subject to variation, the melody follows the lyric form
and is supported by a fixed harmonic progression. Phrases are typically
four measures long, making the entire "chorus" 12 bars.
C Major Scale (2 octaves)
7th Chords built on scale tones
Basic blues chord progression
Common variations include:
IV chord in measure 10.
a ii chord in measure 9 and a V chord in measure 10.
a IV chord in measure 2.
turnarounds or walking bass figures at the ends of choruses.
Origins of the Blues
Work songs & field hollers - [listening example
"Berta, Berta"]
"Work songs" in a call-and-response form can be traced to African
sources. They were common in the plantation culture; after the breakup
of plantations they diminished in importance except for the southern
penitentiary farms, were they persisted until the 1950s.
Work songs gradually became "field hollers" solo calls that
were comparatively free in form but close to blues in feeling. The vocal
style of the blues probably derived from the holler.
An African American consciousness
The earliest African American folk music was vocal; slaves were not
permitted to bring instruments with them, and drumming was forbidden
on slave plantations. The playing of string instruments was permitted,
however. The banjo, later replaced by the guitar, is probably a direct
descendant of the xalam.
The tradition of musicians as tribal historians and social commentators
continued, at least to a degree, in America; later, blues singers performed
a similar function.
In the last decade of the 19th century, the post-Reconstruction bitterness
of southern whites and the resulting "Jim Crow" laws contributed to
the recognition of an African American identity and a flowering of black
sacred and secular music. Some songs resembled the four-line form of
ballads in the British tradition (i.e., John Henry), but many
show the three-line blues form.
The blues was only one of many possible song forms for a time, but
by the 1920s singers emerged whose sole repertory was the blues. Unlike
the ballads, which featured narrative accounts of famous or legendary
figures, blues singers focused on more personal or basic topics such
as love, death, sexuality, life conditions, etc. "Some blues described
disasters or personal accidents; themes of crime, prostitution, gambling,
alcohol and imprisonment are prominent in early examples and have persisted
ever since. Some blues are tender but few reveal a response to nature;
far more express a desire to move or escape by train or road to an imagined
better land. Many are aggressively sexual, and there is much that is
consciously and subconsciously symbolic of frustration and oppression"
(from New Grove).
Some general characteristics of early blues:
Appeals to senses rather than intellect.
Blue notes and personal inflection.
Free from traditional rhythmic restrictions.
Country Blues vs. City Blues
Guitar accompaniment vs. piano or multiple instruments.
Free form & rhythm vs. 12-bar structure.
Earthy lyrics vs. more sophistication in content &
melody.
Expressive but undeveloped vocals vs. refined &
predetermined.
Roots in work songs vs. minstrelsy & vaudeville shows.
Male performers vs. female.
Informal atmosphere vs. formal (performer/audience clearly defined).
