Christmas music comprises a variety of genres of music normally performed or heard around the Christmas season, which tends to begin in the months leading up the actual holiday and end in the weeks shortly thereafter.

Music was an early feature of the Christmas season and its celebrations. The earliest chants, litanies, and hymns were Latin works intended for use during the church liturgy, rather than popular songs. The 13th century saw the rise of the carol written in the vernacular, under the influence of Francis of Assisi.

In the Middle Ages, the English combined circle dances with singing and called them carols. Later, the word carol came to mean a song in which a religious topic is treated in a style that is familiar or festive. From Italy, it passed to France and Germany, and later to England. Christmas carols in English first appear in a 1426 work of John Audelay, a Shropshire priest and poet, who lists 25 "caroles of Cristemas", probably sung by groups of wassailers, who went from house to house. Music in itself soon became one of the greatest tributes to Christmas, and Christmas music includes some of the noblest compositions of the great musicians.

Andrea Bocelli, OMRI, OMDSM (Italian pronunciation: [anˈdrɛːa boˈtʃɛlli]; born 22 September 1958) is an Italian tenor, multi-instrumentalist and classical crossover artist. Born with poor eyesight, he became blind at the age of twelve following a football accident.

Since winning the Newcomers section of the Sanremo Music Festival in 1994, Bocelli has recorded thirteen solo studio albums, of both pop and classical music, two greatest hits albums, and eight complete operas, selling over 75 million records worldwide. Thus, he is the biggest-selling solo artist in the history of classical music and has caused core classical repertoire to "cross over" to the top of international pop charts and into previously uncharted territory in popular culture.

In 1998, he was named one of People Magazine's 50 Most Beautiful People. In 1999, his nomination for Best New Artist at the Grammy Awards marked the first, and so far only time a classical artist had been nominated in the category, since Leontyne Price, in 1961.The Prayer, his duet with Celine Dion for the animated film The Quest for Camelot, won the Golden Globe for Best Original Song and was nominated for an Academy Award in the same category. With the release of his classical album, Sacred Arias, Bocelli captured a listing in the Guinness Book of World Records, as he simultaneously held the top 3 positions on the US classical albums charts. Six of his albums have since reached the Top 10 on the Billboard 200, and a record-setting 8, have topped the classical albums charts in the United States.

Morna Anne Murray CC ONS (born June 20, 1945) is a multiple award-winning Canadian singer in pop, country and adult contemporary music whose albums have sold over 54 million copies.

Murray was the first Canadian female solo singer to reach #1 on the U.S. charts, and also the first to earn a Gold record for one of her signature songs, "Snowbird" (1970). She is often cited as the woman who paved the way for other Canadian international success stories such as Céline Dion, Sarah McLachlan and Shania Twain. She is also the first woman and the first Canadian to win "Album of the Year" at the Country Music Association Awards for her 1984 album A Little Good News.

Murray has received four Grammy Awards, 24 Juno Awards (she holds the record for the most Junos awarded to an artist), three American Music Awards, three Country Music Association Awards and three Canadian Country Music Association Awards. She has been inducted into the Canadian Country Music Hall of Fame, the Juno Hall of Fame, The Songwriters Hall of Fame and the Hit Parade Hall of Fame. She is a member of the Country Music Hall of Fame Walkway of Stars in Nashville, and has her own star on the Hollywood Walk of Fame in Los Angeles and on Canada's Walk of Fame in Toronto.

Francis Albert "Frank" Sinatra,  /sɨˈnɑːtrə/, (December 12, 1915 – May 14, 1998) was an American singer and film actor.

Beginning his musical career in the swing era with Harry James and Tommy Dorsey, Sinatra became an unprecedentedly successful solo artist in the early to mid-1940s, after being signed to Columbia Records in 1943. Being the idol of the "bobby soxers", he released his first album, The Voice of Frank Sinatra in 1946. His professional career had stalled by the 1950s, but it was reborn in 1953 after he won the Academy Award for Best Supporting Actor for his performance in From Here to Eternity.

He signed with Capitol Records in 1953 and released several critically lauded albums (such as In the Wee Small Hours, Songs for Swingin' Lovers, Come Fly with Me, Only the Lonely and Nice 'n' Easy). Sinatra left Capitol to found his own record label, Reprise Records in 1961 (finding success with albums such as Ring-a-Ding-Ding!, Sinatra at the Sands and Francis Albert Sinatra & Antonio Carlos Jobim), toured internationally, was a founding member of the Rat Pack and fraternized with celebrities and statesmen, including John F. Kennedy. Sinatra turned 50 in 1965, recorded the retrospective September of My Years, starred in the Emmy-winning television special Frank Sinatra: A Man and His Music, and scored hits with "Strangers in the Night" and "My Way".

Mariah Carey (born March 27, 1970) is an American singer, songwriter, record producer, and actress. She made her recording debut in 1990 under the guidance of Columbia Records executive Tommy Mottola, and released her self-titled debut studio album, Mariah Carey. The album went multi-platinum and spawned four consecutive number one singles, on the U.S. Billboard Hot 100 chart. Following her marriage to Mottola in 1993, a series of hit records, including Emotions (1991), Music Box (1993) and Merry Christmas (1994), established her position as Columbia's highest-selling act. Daydream (1995), made music history when the second single, "One Sweet Day" a duet with Boyz II Men, spent a record sixteen weeks on top of the Billboard Hot 100, and remains the longest running number one song in US chart history. During the recording of the album Carey began to deviate from her pop background, and slowly traversed into R&B and Hip-hop. After her separation from Mottola, this musical change was evident with the release of Butterfly (1997).
