Music

According to the Tenth Doctor, with music, one could "dance to it, sing with it, fall in love to it. Unless you're a Dalek of course. Then it's all just noise". (TV: Evolution of the Daleks)

Music could also be defined as a complex flow of notes all played on the same instrument. (PROSE: Sleep) It was seen as an art form. (PROSE: Cold Fusion)

Most forms of music needed to have a rhythmic or thudding beat. (PROSE: Happy Endings, Revolution Man) Rock and roll was one such form. (PROSE: Cat's Cradle: Witch Mark)

Music could also a melodic structure, perhaps upon a rhythmic foundation, complete with chanting. (PROSE: All-Consuming Fire)

Music could be written down on paper as sheet music, or in some cases painted into a painting, as was the case with Rassilon's Lament. (PROSE: Emotional Chemistry, Blood Harvest)

History of music styles
The Seventh Doctor considered Ace's music from her boombox anachronistic in 1963. (TV: Remembrance of the Daleks)

By mid-2596 some music could be classified as "club-generic, layered, white-noise structures, underlaid with low-level, subsonic dynamics operating directly on the limbic system". (PROSE: Return to the Fractured Planet)

At some point in the far future, music consisted of "harsh electronic sounds with a pumping bassline". (PROSE: Hope)
