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 adapted, to music. Musical settings include choral music and other vocal music.[1] A musical setting is made to particular words, such as poems.[2] 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.[3]
Texts commonly used in choral settings include the mass and the requiem in Western Christianity, and the Divine Liturgy of St. John Chrysostom and the All-night vigil in Eastern Christianity. Examples include Mozart's Great Mass, and Leontovych's Liturgy of St. John Chrysostom.
A poem that has been set to music is known as an art song or Lied (German variant). Composers known for their art songs include Franz Schubert and Robert Schumann.
