Sheet music is a handwritten or printed form of music notation that uses modern musical symbols; like its analogs — books, pamphlets, etc. — the medium of sheet music typically is paper (or, in earlier times, parchment), although the access to musical notation in recent years includes also presentation on computer screens. Use of the term "sheet" is intended to differentiate music on paper from an audio presentation, as in a sound recording, broadcast or live performance, which may involve video as well. In everyday use, "sheet music" (or simply "music") can refer to the print publication of commercial music in conjunction with the release of a new film, show, record album, or other special or popular event which involves music.

Score is a common alternative (and more generic) term for sheet music, and there are several types of scores, as discussed below. (Note: the term score can also refer to incidental music written for a play, television programme or film; for the last of these, see film score.)

Christina Judith Perri (born August 19, 1986) is an American singer-songwriter and musician from Philadelphia. Her song "Jar of Hearts" charted in the United States after it was featured on the Fox television show So You Think You Can Dance in 2010.

Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American recording artist, entertainer, and businessman. Often referred to as the King of Pop, or by his initials MJ, Jackson is recognized as the most successful entertainer of all time by Guinness World Records. His contribution to music, dance, and fashion, along with a much-publicized personal life, made him a global figure in popular culture for over four decades. The seventh child of the Jackson family, he debuted on the professional music scene along with his brothers as a member of The Jackson 5 in 1964, and began his solo career in 1971.

In the early 1980s, Jackson became a dominant figure in popular music. The music videos for his songs, including those of "Beat It", "Billie Jean", and "Thriller", were credited with transforming the medium into an art form and a promotional tool, and the popularity of these videos helped to bring the relatively new television channel MTV to fame. Videos such as "Black or White" and "Scream" made him a staple on MTV in the 1990s. Through stage performances and music videos, Jackson popularized a number of complicated dance techniques, such as the robot and the moonwalk, to which he gave the name. His distinctive musical sound and vocal style influenced numerous hip hop, post-disco, contemporary R&B, pop and rock artists.
