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.

Tom Prichard

Thomas "Dr. Tom" Prichard (born August 18, 1959) is an American professional wrestler and author. He is the brother of Chris and Bruce Prichard.

Career

Beginnings

Tom Prichard began his career in Los Angeles, around 1979, working for Gene and Mike LeBell's Los Angeles Olympic Auditorium wrestling promotion, where he held several championships in that organization, including the Americas tag team title with Chris Adams. After LeBell closed the L.A. promotion down in 1982, Prichard competed in various NWA territories for the next four years before settling in the southeast, where he had his greatest success of his career.

Continental Wrestling Federation and United States Wrestling Association

Prichard joined the Continental Wrestling Federation in the late 1980s, and feuded with "The Dirty White Boy" Tony Anthony. Their feud included a very controversial angle, which aired on April 23, 1988, where Anthony's valet came out with a black eye and begged Prichard to help her, only for Anthony to attack him from behind, cuff his hands behind his back, and hang him. On October 3, 1988 in Birmingham, Alabama, he defeated Anthony in the finals of a tournament to win the vacant CWF Heavyweight Championship. Prichard lost the title to Wendell Cooley on April 7, 1989 in Knoxville, Tennessee, but regained the belt on June 23 of that year. He lost the title to Dennis Condrey a month later on July 22 in Dothan, Alabama, before once again regaining it after defeating Condrey on December 6 of that same year. Prichard held the title until the CWF closed later that month.

Convolution (computer science)

In computer science, specifically formal languages, convolution (sometimes referred to as zip) is a function which maps a tuple of sequences into a sequence of tuples.

Example

Given the three words and, fish and be where |and| is 3, |fish| is 4 and |be| is 2. Let denote the longest word which is fish; . The convolution of and, fish, be is then 4 tuples of elements:

where # is a symbol not in the original alphabet. In Haskell this truncates to shortest sequence , where :

Definition

Let Σ be an alphabet, # a symbol not in Σ.

Let x₁x₂... x_|x|, y₁y₂... y_|y|, z₁z₂... z_|z|, ... be n words (i.e. finite sequences) of elements of Σ. Let denote the length of the longest word, i.e. the maximum of |x|, |y|, |z|, ... .

The convolution of these words is a finite sequence of n-tuples of elements of (Σ ∪ {#}), i.e. an element of :

where for any index i > |w|, the w_i is #.

The convolution of x, y, z, ... is denoted conv( x, y, z, ...), zip( x, y, z, ...) or x ⋆ y ⋆ z ⋆ ...

The inverse to convolution is sometimes denoted unzip.
