Sweetness is one of the five basic tastes and is almost universally regarded as a pleasurable experience. Foods rich in simple carbohydrates such as sugar are those most commonly associated with sweetness, although there are other natural and artificial compounds that are sweet at much lower concentrations, allowing their use as non-caloric sugar substitutes. Other compounds may alter perception of sweetness itself.

The chemosensory basis for detecting sweetness, which varies among both individuals and species, has only been teased apart in recent years. A recent theoretical model of sweetness is the multipoint attachment theory, which involves multiple binding sites between a sweetness receptor and a sweet substance.

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.
