Billie Holiday in the context of "Teddy Wilson"

A song is a musical composition performed by the human voice. The voice often carries the melody (a series of distinct and fixed pitches) using patterns of sound and silence. Songs have a structure, such as the common ABA form, and are usually made of sections that are repeated or performed with variation later. A song without instruments is said to be a cappella.

Written words created specifically for music, or for which music is specifically created, are called lyrics. If a pre-existing poem is set to composed music in the classical tradition, it is called an art song. Songs that are sung on repeated pitches without distinct contours and patterns that rise and fall are called chants. Songs composed in a simple style that are learned informally by ear are often referred to as folk songs. Songs composed for the mass market, designed to be sung by professional singers who sell their recordings or live shows, are called popular songs. These songs, which have broad appeal, are often composed by professional songwriters, composers, and lyricists; art songs are composed by trained classical composers for concert or recital performances. Songs are performed in studios and an audio recording is made, or they are performed live for audience. (In some cases a song may be performed live and simultaneously recorded.) Songs may also appear in theatre (e.g., opera), films and TV shows.

John Henry Hammond Jr. (December 15, 1910 – July 10, 1987) was an American record producer, civil rights activist, and music critic active from the 1930s to the early 1980s. As a talent scout, Hammond became one of the most influential figures in 20th-century popular music. He is the father of blues musician John P. Hammond.

Hammond sparked or advanced numerous musical careers, including those of Bob Dylan, Bruce Springsteen, Benny Goodman, Harry James, Charlie Christian, Billie Holiday, Count Basie, Teddy Wilson, Big Joe Turner, Fletcher Henderson, Pete Seeger, Babatunde Olatunji, Aretha Franklin, George Benson, Freddie Green, Leonard Cohen, Arthur Russell, Jim Copp, Asha Puthli, Stevie Ray Vaughan, Mike Bloomfield and Sonny Burke. He is also largely responsible for the revival of delta blues artist Robert Johnson's music.

"What a Little Moonlight Can Do" is a popular song written by Harry M. Woods in 1934. In 1934, Woods moved to London for three years where he worked for the British film studio Gaumont British, contributing material to several films, one of which was Road House (1934). The song was sung in the film by Violet Loraine and included an introductory verse, not heard in the version later recorded by Billie Holiday in 1935.

Lady in Satin is an album by the jazz singer Billie Holiday, released in 1958 on Columbia Records, catalogue CL 1157 in mono and CS 8048 in stereo. It is the penultimate album completed by the singer, and the last to be released in her lifetime. Her final album, Last Recording, was recorded in March 1959, and released just after her death. The original album was produced by Irving Townsend and engineered by Fred Plaut.

"Embraceable You" is a jazz standard song with music by George Gershwin and lyrics by Ira Gershwin. The song was written in 1928 for an unpublished operetta named East Is West. It was published in 1930 and included in that year's Broadway musical Girl Crazy, performed by Ginger Rogers in a song and dance routine choreographed by Fred Astaire.

Billie Holiday's 1944 recording was inducted into the Grammy Hall of Fame in 2005.
