Spoken word refers to an oral poetic performance art that is based mainly on the poem as well as the performer's aesthetic qualities. It is a late 20th century continuation of an ancient oral artistic tradition that focuses on the aesthetics of recitation and word play, such as the performer's live intonation and voice inflection. Spoken word is a "catchall" term that includes any kind of poetry recited aloud, including poetry readings, poetry slams, jazz poetry, and hip hop music, and can include comedy routines and prose monologues. Unlike written poetry, the poetic text takes its quality less from the visual aesthetics on a page, but depends more on phonaesthetics, or the aesthetics of sound.
