+++Blue MusiC+++







Blues has evolved from an unaccompanied vocal music of poor black laborers into a wide variety of styles and subgenres, with regional variations across the United States and, later, Europe and Africa. The musical forms and styles that are now considered the "blues" as well as modern "country music" arose in the same regions during the nineteenth century in the southern United States. Recorded blues and country can be found from as far back as the 1920s, when the popular record industry developed and created marketing categories called "race music" and "hillbilly music" to sell music by and for blacks and whites, respectively.


At the time, there was no clear musical division between "blues" and "country," except for the race of the performer, and even that sometimes was documented incorrectly by record companies.[22] Studies have situated the origin of "black" spiritual music inside slaves' exposure to their masters' Hebridean-originated gospels. African-American economist and historian Thomas Sowell also notes that the southern, black, ex-slave population was acculturated to a considerable degree by and among their Scots-Irish "redneck" neighbours. However, the findings of Kubik and others also clearly attest to the essential Africanness of many essential aspects of blues expression.


There are few characteristics common to all blues, because the genre takes its shape from the idiosyncrasies of individual performances.However, there are some characteristics that were present long before the creation of the modern blues.
An early form of blues-like music was a call-and-response shouts, which were a "functional expression... style without accompaniment or harmony and unbounded by the formality of any particular musical structure A form of this pre-blues was heard in slave field shouts and hollers, expanded into "simple solo songs laden with emotional content".The blues, as it is now known, can be seen as a musical style based on both European
harmonic structure and the West African call-and-response tradition, transformed into an interplay of voice and guitar.
Many blues elements, such as the call-and-response format and the use of blue notes, can be traced back to the
music of Africa. Sylviane Diouf has pointed to several specific traits—such as the use of melisma and a wavy, nasal intonation—that suggest a connection between the music of West and Central Africa and blues.[9] Ethnomusicologist Gerhard Kubik may have been the first to contend that certain elements of the blues have roots in the Islamic music of West and Central Africa.


During the first decades of the twentieth century blues music was not clearly defined in terms of a chord progression. There were many blues in 8-bar form, such as "How Long Blues", "Trouble in Mind", and Big Bill Broonzy's "Key to the Highway". There are also 16 bar blues, as in Ray Charles's instrumental "Sweet 16 Bars", and in Herbie Hancock's "Watermelon Man". More idiosyncratic numbers of bars are also encountered occasionally, as with the 9 bar progression in Howlin' Wolf's "Sitting on top of the World". The basic twelve-bar lyric framework of a blues composition is reflected by a standard harmonic progression of twelve bars, in 4/4 or (rarely) 2/4 time. Slow blues are often played in 12/8 (4 beats per measure with 3 subdivisions per beat).
By the 1930s, twelve-bar blues became more standard. The blues
chords associated to a twelve-bar blues are typically a set of three different chords played over a twelve-bar scheme

Tennessee Valley Authority





+++++The Tennessee Valley Authority (TVA) ++++++



A federally owned corporation in the United States created in May 1933 to provide navigation, flood control, electricity generation, fertilizer manufacturing, and economic development in the Tennessee Valley, a region particularly hard hit by the Great Depression.


The TVA was envisioned not only as an electricity provider, but also as a regional economic development agency that would use federal experts and electricity to rapidly modernize the region's economy and society. The TVA's jurisdiction covers most of Tennessee, parts of Alabama, Mississippi and Kentucky, and small slices of Georgia, North Carolina and Virginia. It is a geopolitical entity with a territory the size of a major state, and with some state powers (such as eminent domain), but unlike a state it has no citizenry or elected officials. It was the first large regional planning agency of the federal government and remains the largest. Under the leadership of David Lilienthal ("Mr. TVA"), the Authority became a model for American efforts to modernize Third World agrarian societies.++++


During the 1920 and the Great Depression years Americans began to support the idea of government ownership of utilities, particularly hydroelectric power facilities. The concept of government-owned generation facilities selling to publicly owned distribution utilities was controversial and remains so today (Hubbard, pp 5-27).
Many believed privately owned power companies were charging too much for power, did not employ fair operating practices, and were subject to abuse by their owners (utility holding companies), at the expense of consumers. During his presidential campaign Roosevelt claimed that private utilities had "selfish purposes" and said, "Never shall the federal government part with its sovereignty or with its control of its power resources while I'm president of the United States." By forming utility holding companies, the private sector controlled 94 percent of generation by
1921, essentially unregulated. (This gave rise to Public Utility Holding Company Act of 1935 (PUHCA)). Many private companies in the Tennessee Valley were bought by the federal government. Others shut down, unable to compete with the TVA. Government regulations were also passed to prevent competition with the TVA.
On the other hand there were conservatives who believed the government should not participate in the electricity generation business, fearing government ownership would lead to the misuse of hydroelectric sites. The TVA was one of the first federal
hydropower agencies, and today most of the nation's major hydropower systems are federally managed. Attempts to create TVA-like regional agencies failed, such as a proposed Columbia Valley Authority for the Columbia River.
