Rock Backgrounds

Rock music — or simply rock — is a loosely defined genre of popular music that developed during and after the 1960s. It has its roots in 1940s and 1950s rock and roll and rockabilly, which themselves evolved from blues, country music and other influences. In addition, rock music drew on a number of other musical influences, including folk music, jazz, and classical music.

The sound of rock often revolves around the electric guitar or acoustic guitar, and it uses a strong back beat laid down by a rhythm section of electric bass guitar, drums, and keyboard instruments such as organ, piano, or, since the 1970s, synthesizers. Along with the guitar or keyboards, saxophone and blues-style harmonica are sometimes used as soloing instruments. In its "purest form", it "has three chords, a strong, insistent back beat, and a catchy melody."

Here are some rock backgrounds.

Brown Backgrounds

Brown, when used as a general term, is a color that is a dark yellow, orange, or red, of low luminance relative to lighter or white colored objects. Some amber and yellow colors of lower saturation are called light browns. These are several samples of brown backgrounds.

A city is an urban area with a high population and a particular administrative, legal, or historical status. Here are some cool city background around the world. City backgrounds are great especially the light when sunrise, sunset, and in the night.

Cool is an aesthetic of attitude, behavior, comportment, appearance, style and Zeitgeist. Because of the varied and changing connotations of cool, as well its subjective nature, the word has no single meaning. It has associations of composure and self-control (cf. the OED definition) and often is used as an expression of admiration or approval.

Spring backgrounds

Spring backgrounds

According to an astronomical definition, spring begins on the vernal equinox (usually September 21 in the Southern Hemisphere, and March 20 in the Northern Hemisphere), and lasts until the summer solstice (usually December 21 in the Southern Hemispherre and June 21 in the Northern Hemisphere). According to this definition, therefore, the day called Midsummer's Day in some traditions, is close to the first day of Summer. An alternative tradition is to calculate Spring as starting on March 1 in the Northern Hemisphere and September 1 in the Southern Hemisphere. The lower (cooler) latitudes are more inclined to start with the later date, vernal equinox, while the higher (warmer) latitudes, where the biological indicators of spring arrive earlier, are more inclined to run with the 1st of the month. According to a less used solar term, spring begins on February 4 and ends on May 4, and calendars may give the first, but the second and third are more used with this tradition.

The phenological definition of spring relates to bioindicators, the blossoming of a range of plant species, and the activites of animals, or the special smell of soil that has reached the temperature for microflora to flourish. The first swallow to arrive or the flowering of lilac may be the indicator of spring. A number of meterological stations have planted Syringa rothamagensis, and the date of full flowering, as determined by defined means, is used as a more precise indicator of the date of start of spring for agricultural activities associated with spring and the passing of frosty weather. It therefore varies according to the climate (as in 'Spring comes late to the north-east'), and according the to specific weather of particular years (as in 'this was an unusually early spring for our area with all these extra days of warm winds, fewer frosts at this time of the year, and with the early flowering of the lilac, and early arrival of the swallows; we therefore planted longer season varieties to extend our growing season and get greater yields.')

Barack Hussein Obama II [born August 4, 1961) is the junior United States Senator from Illinois. He is the presumptive nominee of the Democratic Party in the 2008 presidential election, and the first African American to be a major party's presumptive nominee for President of the United States.

A graduate of Columbia University and Harvard Law School, Obama worked as a community organizer and practiced as a civil rights attorney before serving in the Illinois Senate from 1997 to 2004. He also taught constitutional law at the University of Chicago Law School from 1992 to 2004. Following an unsuccessful bid for a seat in the U.S. House of Representatives in 2000, he announced his campaign for the U.S. Senate in January 2003. After winning a landslide primary victory in March 2004, Obama delivered the keynote address at the Democratic National Convention in July 2004. He was elected to the Senate in November 2004 with 70% of the vote.

He also made official trips to Eastern Europe, the Middle East, and Africa. In the current 110th Congress, he has sponsored legislation regarding lobbying and electoral fraud, climate change, nuclear terrorism, and care for returned U.S. military personnel. Since announcing his presidential campaign in February 2007, Obama has emphasized withdrawing American troops from Iraq, increasing energy independence, decreasing the influence of lobbyists, and promoting universal health care as top national priorities.

Blue is a colour, the perception of which is evoked by light having a spectrum dominated by energy with a wavelength of roughly 440–490 nm. It is considered one of the additive primary colours. On the HSV Colour Wheel, the complement of blue is yellow; that is, a colour corresponding to an equal mixture of red and green light. On a colour wheel based on traditional colour theory (RYB), the complementary colour to blue is considered to be orange (based on the Munsell colour wheel). The English language commonly uses "blue" to refer to any colour from navy blue to cyan. The word itself is derived from the French word bleu.

Black is the color of objects that do not emit or reflect light in any part of the visible spectrum; they absorb all such frequencies of light. Although black is sometimes described as an "achromatic", or hueless, color, in practice it can be considered a color, as in expressions like "black cat" or "black paint".

Black can be defined as the visual impression experienced when no visible light reaches the eye. (This makes a contrast with whiteness, the impression of any combination of colors of light that equally stimulates all three types of color-sensitive visual receptors.)

Pigments that absorb light rather than reflect it back to the eye "look black". A black pigment can, however, result from a combination of several pigments that collectively absorb all colors. If appropriate proportions of three primary pigments are mixed, the result reflects so little light as to be called "black".
