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.)

The Basics ( /ˈbæzɪtʃ/ BAZZ-ich) are a three-piece band from Melbourne, Australia, formed by Wally De Backer and Kris Schroeder in 2002. Their style has been described as anything from 'indie-pop' to 'rock'n'roll' to 'pop-rock', though their records show they span a wide range of genres, including reggae, ska, country, and electro-pop. They are "recognised as one of Australia's hardest-working bands".

With close to 1000 shows in their ten-year career, their live performances are well-known for their sense of humour and energy.

The Basics were formed after Kris met Wally at a party in Melbourne. The event was to see off the young aspiring producer, who was about to depart for Los Angeles, and together with a number of musician friends, the two jammed on some blues-rock standards. Later that night, they bonded over a mutual love of The Beatles, 70s and 80s cartoon theme songs and old Sierra adventure games.

Initially, they played around Melbourne as an acoustic guitar/drums combo, starting at The Opposition in Frankston and the House of Fools in Footscray, where in late 2002 they met Michael Hubbard and later invited him to join them on electric guitar. Though lacking any real experience with the instrument, Kris willingly purchased his first bass guitar, and the trio was born. During this time, the group start performing songs with more complicated three-part harmony.
