Set (music)

A set (pitch set, pitch-class set, set class, set form, set genus, pitch collection) in music theory, as in mathematics and general parlance, is a collection of objects. In musical contexts the term is traditionally applied most often to collections of pitches or pitch-classes, but theorists have extended its use to other types of musical entities, so that one may speak of sets of durations or timbres, for example.

A set by itself does not necessarily possess any additional structure, such as an ordering. Nevertheless, it is often musically important to consider sets that are equipped with an order relation (called segments); in such contexts, bare sets are often referred to as "unordered", for the sake of emphasis.

Two-element sets are called dyads, three-element sets trichords (occasionally "triads", though this is easily confused with the traditional meaning of the word triad). Sets of higher cardinalities are called tetrachords (or tetrads), pentachords (or pentads), hexachords (or hexads), heptachords (heptads or, sometimes, mixing Latin and Greek roots, "septachords"—e.g.,), octachords (octads), nonachords (nonads), decachords (decads), undecachords, and, finally, the dodecachord.

Set construction

Set construction is the process by which a construction manager undertakes to build full scale scenery suitable for viewing by camera, as specified by a production designer or art director working in collaboration with the director of a production to create a set for a theatrical, film or television production. The set designer produces a scale model, scale drawings, paint elevations (a scale painting supplied to the scenic painter of each element that requires painting), and research about props, textures, and so on. Scale drawings typically include a groundplan, elevation, and section of the complete set, as well as more detailed drawings of individual scenic elements which, in theatrical productions, may be static, flown, or built onto scenery wagons. Models and paint elevations are frequently hand-produced, though in recent years, many Production Designers and most commercial theatres have begun producing scale drawings with the aid of computer drafting programs such as AutoCAD or Vectorworks.

Associative containers

In computing, associative containers refer to a group of class templates in the standard library of the C++ programming language that implement ordered associative arrays. Being templates, they can be used to store arbitrary elements, such as integers or custom classes. The following containers are defined in the current revision of the C++ standard: set, map, multiset, multimap. Each of these containers differ only on constraints placed on their elements.

The associative containers are similar to the unordered associative containers in C++ standard library, the only difference is that the unordered associative containers, as their name implies, do not order their elements.

Characteristics

Born to Die (Lana Del Rey album)

Born to Die is the second studio album and major-label debut by American singer and songwriter Lana Del Rey. It was released on January 27, 2012 by Interscope Records, Polydor Records, and Stranger Records. Del Rey collaborated with producers including Patrik Berger, Jeff Bhasker, Chris Braide, Emile Haynie, Justin Parker, Rick Nowels, Robopop, and Al Shux to achieve her desired sound. Their efforts resulted in a primarily baroque pop record, which sees additional influences from alternative hip hop, indie pop and trip hop music.

Contemporary music critics were divided in their opinions of Born to Die; some commended its distinctive production, while its repetitiveness and melodramatic tendencies were a recurring complaint. The record debuted at number two on the U.S. Billboard 200 with first-week sales of 77,000 copies; it was later certified platinum by the Recording Industry Association of America (RIAA) after moving one million units. Born to Die reached the peak position on eleven international record charts, and has sold 8.5 million copies worldwide as of May 2015.

Radio (Darius Rucker song)

"Radio" is a song co-written and recorded by American country music artist Darius Rucker. It was released on July 22, 2013 as the third single from his album True Believers. Rucker wrote the song with Luke Laird and Ashley Gorley.

Content

The song is a reflection on the narrator's teenage years: specifically, of borrowing his mother's car to take his girlfriend for a ride, and listening to songs on the radio while doing so.

Critical reception

The song generally received favorable reviews. Bobby Peacock of Roughstock gave the song four and a half stars out of five, saying that "it sounds like the kind of fun song you would want to hear on the radio at a memorable moment." Peacock praised Rucker's "all-smiles delivery" and the song's "incredibly catchy melody and tight production." He also compared its theme to "I Watched It All (On My Radio)" by Lionel Cartwright. Tammy Ragusa of Country Weekly gave the song an A grade, calling it "the perfect marriage of an artist’s effervescent personality with an upbeat song, this one about the love of music." Billy Dukes of Taste of Country gave the song two and a half stars out of five, writing that "the uptempo tribute to young love, open roads and, of course, the radio is familiar and easy to fall for, especially when powered by Rucker’s unequaled exuberance." However, Dukes also called the song "a little fluffy" and "not difficult to forget."

Radioactive (Yelawolf album)

Radioactive (also known as Radioactive: Amazing and Mystifying Chemical Tricks) is the debut studio album by American rapper Yelawolf; it was released on November 21, 2011, by Shady Records and Interscope Records.

Music composition, style, and lyrics

Radioactive covers many different styles of hip hop fusions, being alternative hip hop as principal musical genre. Hardcore hip hop is represented on the tracks "Radioactive Introduction", "Throw It Up", "Get Away", and "Slumerican Shitizen". A horrorcore rap style is used in "Growin' Up in the Gutter", whereas "Hard White (Up in the Club)" is a crunk party track. "Let's Roll", "Write Your Name", and "Radio" follow a pop rap style, with catchy hooks and beats. "Animal" is a fast-paced hip hop party track with a dubstep influenced beat. "Good Girl" utilizes an R&B-tinged feel, while "The Hardest Love Song in the World" is a g-funk hip hop track. Yelawolf covers a variety of lyrical themes in these album, from gangsta rap lyrics in "Get Away" and "Throw It Up", to more conscious and slightly political tracks such as "Made in the USA", "Slumerican Shitizen", "Write Your Name", and "The Last Song". "Radio" is about the internet taking over how music and music videos are received by fans. It also refers to radio stations playing the same songs constantly and singers being discovered via the internet. The song contains several references to rock and rap artists and their songs from the past. The album's final track, titled "The Last Song" described as very personal about Yelawolf's life, and it's a very emotional final letter to his absent biological father and talks about other past struggles.
