5 (number)

5 (five /ˈfaɪv/) is a number, numeral, and glyph. It is the natural number following 4 and preceding 6.

In mathematics

Five is the third prime number. Because it can be written as 2²¹ + 1, five is classified as a Fermat prime; therefore a regular polygon with 5 sides (a regular pentagon) is constructible with compass and unmarked straightedge. 5 is the third Sophie Germain prime, the first safe prime, the third Catalan number, and the third Mersenne prime exponent. Five is the first Wilson prime and the third factorial prime, also an alternating factorial. Five is the first good prime. It is an Eisenstein prime with no imaginary part and real part of the form 3n − 1. It is also the only number that is part of more than one pair of twin primes. Five is a congruent number.

Five is conjectured to be the only odd untouchable number and if this is the case then five will be the only odd prime number that is not the base of an aliquot tree.

The number 5 is the fifth Fibonacci number, being 2 plus 3. 5 is also a Pell number and a Markov number, appearing in solutions to the Markov Diophantine equation: (1, 2, 5), (1, 5, 13), (2, 5, 29), (5, 13, 194), (5, 29, 433), ... ( A030452 lists Markov numbers that appear in solutions where one of the other two terms is 5). Whereas 5 is unique in the Fibonacci sequence, in the Perrin sequence 5 is both the fifth and sixth Perrin numbers.

History

Formation and Swan Songs (2005–2009)

The band originated on June 3, 2005 as The Kids from a song titled "Hollywood" (Later released as "The Kids") that Jorel Decker (J-Dog), Aron Erlichman (Deuce), and Jeff Phillips (Shady Jeff) posted on the band's MySpace profile to positive reviews, leading them to form the group Hollywood Undead with their friends George "Johnny 3 Tears" Ragan, Jordon "Charlie Scene" Terrell, Dylan "Funny Man" Alvarez, and Matthew "Da Kurlzz" Busek. In an interview with Shave magazine, J-Dog explained that when forming the band "Whoever was in the room at the time and played an instrument was in the band." Phillips later left the group because of conflict with Erlichman.

Philip Glass

Philip Morris Glass (born January 31, 1937) is a classical American composer. He is considered one of the most influential music makers of the late 20th century. His music is also often controversially described as minimal music, along with the work of the other "major minimalists" La Monte Young, Terry Riley and Steve Reich.

Glass has distanced himself from the "minimalist" label, describing himself instead as a composer of "music with repetitive structures". Though his early mature music shares much with what is normally called "minimalist", he has since evolved stylistically. Currently, he describes himself as a "classicist", pointing out that he is trained in harmony and counterpoint and studied such composers as Franz Schubert, Johann Sebastian Bach, and Wolfgang Amadeus Mozart with Nadia Boulanger.

Glass has founded his namesake musical group, the Philip Glass Ensemble, with which he still performs on keyboards, and has written operas, musical theatre works, ten symphonies, eleven concertos, solo works, chamber music including seven string quartets and instrumental sonatas, and film scores. Three of his film scores have been nominated for Academy Awards.

Blues

Blues is a genre and musical form that originated in African-American communities in the "Deep South" of the United States around the end of the 19th century. The genre developed from roots in traditional African music, combined with European American folk music. Blues incorporated spirituals, work songs, field hollers, shouts, and chants, and rhymed simple narrative ballads. The blues form, ubiquitous in jazz, rhythm and blues and rock and roll, is characterized by the call-and-response pattern, the blues scale and specific chord progressions, of which the twelve-bar blues is the most common. The blue notes (or "worried notes") which are often thirds or fifths which are flatter in pitch than in other music styles, are also an important part of the sound. Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect called a groove.

Blues as a genre possesses other characteristics such as lyrics, bass lines, and instruments. The lyrics of early traditional blues verses consisted of a single line repeated four times. It was only in the first decades of the 20th century that the most common current structure became standard: the so-called AAB pattern, consisting of a line sung over the four first bars, its repetition over the next four, and then a longer concluding line over the last bars. Early blues frequently took the form of a loose narrative, often relating troubles experienced within African American society.
