Triangle (musical instrument)

The triangle is an idiophone type of musical instrument in the percussion family. It is a bar of metal, usually steel but sometimes other metals like beryllium copper, bent into a triangle shape. The instrument is usually held by a loop of some form of thread or wire at the top curve. It was first made around the 16th century.

Shaping

On a triangle instrument, one of the angles is left open, with the ends of the bar not quite touching. This causes the instrument to be of indeterminate or not settled or decided pitch. It is either suspended from one of the other corners by a piece of, most commonly, fishing line, leaving it free to vibrate, or hooked over the hand. It is usually struck with a metal beater, giving a high-pitched, ringing tone.

Although the shape is today generally in the form of an equilateral triangle, early instruments were often formed as isosceles triangles. In the early days the triangles did not have an opening and had jingling rings along the lower side.

Music

Music is an art form and cultural activity whose medium is sound and silence. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and with vocal techniques ranging from singing to rapping, and there are solely instrumental pieces, solely vocal pieces and pieces that combine singing and instruments. The word derives from Greek μουσική (mousike; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound."

Music (Erick Sermon and Marvin Gaye song)

"Music" is a 2001 hit single by Erick Sermon featuring archived vocals from Marvin Gaye.

The song was thought of by Sermon after buying a copy of Gaye's Midnight Love and the Sexual Healing Sessions album, which overlook some of the original album's earlier mixes. After listening to an outtake of Gaye's 1982 album track, "Turn On Some Music" (titled "I've Got My Music" in its initial version), Sermon decided to mix the vocals (done in a cappella) and add it into his own song. The result was similar to Natalie Cole's interpolation of her father, jazz great Nat "King" Cole's hit, "Unforgettable" revisioned as a duet. The hip hop and soul duet featuring the two veteran performers was released as the leading song of the soundtrack to the Martin Lawrence & Danny DeVito comedy, "What's the Worst That Could Happen?" The song became a runaway success rising to #2 on Billboard's R&B chart and was #1 on the rap charts. It also registered at #21 pop giving Sermon his highest-charted single on the pop charts as a solo artist and giving Gaye his first posthumous hit in 10 years following 1991's R&B-charted single, "My Last Chance" also bringing Gaye his 41st top 40 pop hit. There is also a version that's played on Adult R&B stations that removes Erick Sermon's rap verses. The song was featured in the 2011 Matthew McConaughey film The Lincoln Lawyer.

Research Triangle

Coordinates: 35°53′N 78°47′W / 35.88°N 78.79°W / 35.88; -78.79

The Research Triangle, commonly referred to as simply The Triangle, is a region in the Piedmont of North Carolina in the United States, anchored by North Carolina State University, Duke University, University of North Carolina at Chapel Hill, and the cities of Raleigh and Durham and the towns of Cary and Chapel Hill. The eight-county region, officially named the Raleigh–Durham–Cary–Chapel Hill combined statistical area (CSA), comprises the Raleigh-Cary and Durham–Chapel Hill metropolitan areas and the Dunn, Henderson, Oxford, and Sanford Micropolitan Statistical Areas. A 2013 Census estimate put the population at 2,037,430, making it the second largest metropolitan area in the state of North Carolina behind Charlotte. The Raleigh–Durham television market includes a broader 24-county area which includes Fayetteville, and has a population of 2,726,000 persons.

The "Triangle" name was cemented in the public consciousness in the 1950s with the creation of Research Triangle Park, home to numerous high-tech companies and enterprises. Although the name is now used to refer to the geographic region, "the Triangle" originally referred to the universities, whose research facilities, and the educated workforce they provide, have historically served as a major attraction for businesses located in the region. The region should not be confused with The Triad, which is a North Carolina region adjacent to and directly west of the Triangle comprising Greensboro, Winston-Salem, and High Point, among other cities.

Triangle (band)

Triangle (トライアングル, Toraianguru) was a Japanese pop group that formed and debuted in the late 1970s. They released their first single, Triangle Love Letter in mid 1978 and their last single, Koi wa Tekkiri Ba-Bi-Bu-Be-Bo in 1980. The group only released two albums, Triangle Love Letter and Sanjūsō / Triangle 2 in 1978 and 1979 respectively. Sony Music Entertainment released Triangle Single Collection in 2008.

Special right triangle

A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle. A "side-based" right triangle is one in which the lengths of the sides form ratios of whole numbers, such as 3 : 4 : 5, or of other special numbers such as the golden ratio. Knowing the relationships of the angles or ratios of sides of these special right triangles allows one to quickly calculate various lengths in geometric problems without resorting to more advanced methods.

Angle-based

"Angle-based" special right triangles are specified by the relationships of the angles of which the triangle is composed. The angles of these triangles are such that the larger (right) angle, which is 90 degrees or π/2 radians, is equal to the sum of the other two angles.

The side lengths are generally deduced from the basis of the unit circle or other geometric methods. This approach may be used to rapidly reproduce the values of trigonometric functions for the angles 30°, 45°, and 60°.
