Arrangement
An
arrangement is an adaptation of a piece of
music for another musical application than for which it was originally meant. This includes arrangements for a different
instrument, or different instruments (for example an arrangement for
piano or
flute, or a
duet, based on a
symphonic piece; or arrangement of instrumental
accompaniment for
vocal music) and for another musical style (for example adaptation of a
classical piece into a more modern style of music). Sometimes an arrangement is called an
orchestration.
