In music, an ostinato (derived from Italian: "stubborn", compare English: obstinate) is a motif or phrase, which is persistently repeated in the same musical voice. An ostinato is always a succession of equal sounds, wherein each note always has the same weight or stress. The repeating idea may be a rhythmic pattern, part of a tune, or a complete melody in itself. Both "ostinatos" and "ostinati" are accepted English plural forms, the latter reflecting the word's Italian etymology. Strictly speaking, ostinati should have exact repetition, but in common usage, the term covers repetition with variation and development, such as the alteration of an ostinato line to fit changing harmonies or keys.

Ostinati are used in 20th-century music to stabilize groups of pitches, as in Stravinsky's The Rite of Spring "Introduction" and "Augurs of Spring". A famous type of ostinato, called the Rossini crescendo, owes its name to the crescendo underlying a persistent musical pattern, which usually culminates in a solo vocal cadenza. This style was emulated by other bel canto composers, especially Bellini; and later by Wagner (in pure instrumental terms, discarding the closing vocal cadenza). Mozart uses an ostinato phrase throughout the big scene that ends Act 2 of the "Marriage of Figaro", to convey a sense of suspense as the jealous Count Almaviva tries in vain to incriminate the Countess, his wife, and Figaro, his butler, for plotting behind his back.

Stayve Jerome Thomas (born September 8, 1980), better known as Slim Thug, Boss Hogg or Thug Boss, is an American rapper. He gained mainstream attention for his contribution to the popular single from rapper Mike Jones, "Still Tippin'".

Slim Thug grew up in Houston's Northside neighborhood of Homestead/Scenic Woods. Slim says that his rap name come from the fact that as a teenager, he was very tall and skinny before he filled out.^{[citation needed]} He stands 6'6" tall. The Thug part comes from people's assumptions of him due to his fresh braids and sunglasses.^{[citation needed]} At age 17, he performed freestyle raps at local high school parties. He began his rap career with Swishahouse in the late 1990s. After realizing how much money he could make distributing his own mixtapes, he parted ways with Swishahouse on good terms and formed his own independent label, Boss Hogg Outlawz. Thomas bought two record stores and worked in real estate.

Slim Thug's debut album with Star Trak Entertainment & Interscope Records, Already Platinum, was released in July 2005 after many delays. It premiered on #2 on the Billboard 200 albums chart and sold 130,000 copies in its first week. Singles included "3 Kings" (featuring T.I. and Bun B), and "I Ain't Heard of That" (featuring Pharrell and Bun B). Slim Thug appeared on Still Tippin' with Mike Jones and Paul Wall, Beyoncé Knowles's #1 single "Check on It" and Gwen Stefani's "Luxurious". With the Boss Hogg Outlawz, Slim Thug released three albums, Boyz N Blue (2004), Serve & Collect (2007) and Back by Blockular Demand: Serve & Collect II (2008). He left Star Trak & Interscope Records in 2008.

Paul Michael Slayton (born March 11, 1981), better known by his stage name Paul Wall, is an American rapper. He is currently affiliated with Swishahouse Records, having released several albums under the label as well as collaborating with other rappers signed to the label. He was formerly musical partners with rapper Chamillionaire releasing several collaborative albums including the independently released Get Ya Mind Correct. In 2005, he was signed to Atlantic Records and became successful with his major-label debut The Peoples Champ. Get Money, Stay True followed in 2007.

Wall attended Jersey Village High School and studied mass communications at the University of Houston for three years. After proposing to do promotions for Michael "5000" Watts' company, Swishahouse, Chamillionaire and Paul Wall came to Watts' studio, KBXX. Paul & Chamillionaire convinced Watts to let them rap on his radio show and put the verses on one of his mixtapes. That mixtape was titled Choppin Em Up Part 2, which was released in mid 1999. The freestyle became so popular in the streets that Chamillionaire and Paul Wall became regular staples on Houston's mixtape circuit, appeared on several of Watts' mixtapes and became permanent members of Swishahouse.

"The Man" is a slang phrase that may refer to the government or to some other authority in a position of power. In addition to this derogatory connotation, it may also serve as a term of respect and praise.

The phrase "the Man is keeping me down" is commonly used to describe oppression. The phrase "stick it to the Man" encourages resistance to authority, and essentially means "fight back" or "resist", either openly or via sabotage.

The earliest recorded use^{[citation needed]} of the term "the Man" in the American sense dates back to a letter written by a young Alexander Hamilton in September 1772, when he was 15. In a letter to his father James Hamilton, published in the Royal Dutch-American Gazette, he described the response of the Dutch governor of St. Croix to a hurricane that raked that island on August 31, 1772. "Our General has issued several very salutary and humane regulations and both in his publick and private measures, has shewn himself the Man." ^{[dubious – discuss]} In the Southern U.S. states, the phrase came to be applied to any man or any group in a position of authority, or to authority in the abstract. From about the 1950s the phrase was also an underworld code word for police, the warden of a prison or other law enforcement or penal authorities.
