Melisma, in music, is the singing of a single syllable of text while moving between several different notes in succession. Music sung in this style is referred to as melismatic, as opposed to syllabic, where each syllable of text is matched to a single note.

Music of ancient cultures used melismatic techniques to induce a hypnotic trance in the listener, useful for early mystical initiation rites (such as Eleusinian Mysteries) and religious worship. This complex quality is still found most famously in Arabic music where the scale is said to consist of "quarter tones". Orthodox Christian chanting also bears a slight resemblance to this. Middle Eastern melismatic music was developed further in the Torah chanting as well as by the Masoretes in the 7th or 8th century. It then appeared in some genres of Gregorian chant where it was used in certain sections of the Mass, with the earliest written appearance around AD 900. The gradual and the alleluia, in particular, were characteristically melismatic, for example, while the tract is not, and repetitive melodic patterns were deliberately avoided in the style. The Byzantine Rite also used melismatic elements in its music, which developed roughly concurrently to the Gregorian chant.

Brian McKnight (born June 5, 1969) is an American singer-songwriter, arranger, producer, and R&B musician. He is a multi-instrumentalist who plays eight instruments including piano, guitar, bass guitar, percussion, trombone, tuba, flugelhorn and trumpet.. McKnight is perhaps most recognized for his strong falsetto range, and is widely regarded as one of the strongest talents in the adult urban contemporary R&B genre, although his recent efforts have received mixed reviews.

McKnight's work has earned him 16 Grammy Awards nominations, but currently holds the record for having won none.

McKnight was born in Buffalo, New York. His musical career began in childhood when he became a member of his church choir and a band leader for his high school, Sweet Home High School..

In 1987, McKnight's older brother, Claude McKnight III, and his band, Take 6, signed a record deal with Warner Brothers. This encouraged McKnight to shop his own demo tapes and by the age of 19, he'd signed his first recording deal with Mercury Records subsidiary, Wing Records. In 1992, Brian McKnight was released, and his self-titled debut peaked at fifty-eight in the Billboard 200 chart, which primarily featured the ballad (and top twenty single) "One Last Cry". It was followed by two more albums for Mercury, 1995's I Remember You and 1997's Anytime. Anytime, McKnight's final album with Mercury, sold over two million copies and was nominated for a Grammy. The video for "Anytime", directed by Darren Grant, was nominated for Best Male Video at the 1998 MTV Video Music Awards.

Whitney Elizabeth Houston (August 9, 1963 – February 11, 2012) was an American recording artist, actress, producer, and model. In 2009, the Guinness World Records cited her as the most-awarded female act of all-time. Houston was one of the world's best-selling music artists, having sold over 170 million albums, singles and videos worldwide. She released seven studio albums and three movie soundtrack albums, all of which have diamond, multi-platinum, platinum or gold certification. Houston's crossover appeal on the popular music charts, as well as her prominence on MTV, starting with her video for "How Will I Know", influenced several African American female artists to follow in her footsteps.

Houston is the only artist to chart seven consecutive No. 1 Billboard Hot 100 hits. She is the second artist behind Elton John and the only female artist to have two number-one Billboard 200 Album awards (formerly "Top Pop Album") on the Billboard magazine year-end charts. Houston's 1985 debut album Whitney Houston became the best-selling debut album by a female act at the time of its release. The album was named Rolling Stone's best album of 1986, and was ranked at number 254 on Rolling Stone's list of the 500 Greatest Albums of All Time. Her second studio album Whitney (1987) became the first album by a female artist to debut at number one on the Billboard 200 albums chart.

In 1999, Aguilera came to prominence following her debut album Christina Aguilera, which was a commercial success spawning three number one singles on the Billboard Hot 100—"Genie in a Bottle", "What a Girl Wants", and "Come On Over Baby (All I Want Is You)." Her sophomore and her debut Latin-pop album, Mi Reflejo (2000), a Christmas third studio album, My Kind of Christmas (2000), and several collaborations followed which garnered Aguilera worldwide success, though she was displeased with her lack of input in her music and image. After parting from her management, Aguilera took creative control over her fourth studio album, Stripped (2002). The album's second single, "Beautiful", was a commercial success and helped the album's commercial performance amidst controversy over Aguilera's image. Aguilera followed up Stripped with the soul, jazz and blues inspired, Back to Basics (2006), released to positive critical acclaim. The album produced three singles "Ain't No Other Man", "Hurt" and "Candyman". Four years later Aguilera released her sixth studio album, Bionic (2010), which incorporated aspects of R&B, electropop, and synthpop and was met with mixed reviews and low sales. Aguilera's seventh studio album is set to be released in 2012.
