Musical setting

A musical setting is a musical composition that is written on the basis of a literary work. The literary work is said to be set, or adapated, to music. Musical settings include choral music and other vocal music. A musical setting is made to particular words, such as poems. By contrast, a musical arrangement is a musical reconceptualization of a previously composed work, rather than a brand new piece of music. An arrangement often refers to a change in medium or style and can be instrumental, not necessarily vocal music.
