What is Arrangement (music)?
An '''arrangement''' of a musical [[composition (music)|composition]] is a reworking of a piece of music so that it can be played by a different instrument or combination of instruments from the original. For example, a song written for one voice with piano [[accompaniment (music)|accompaniment]] might be arranged so that it can be sung in parts by a [[choir (music)|choir]], or a piece for [[violin]] might be arranged so that it can be played on a clarinet instead. The person who does the arrangement may be the composer themself, or it may be someone else. In music history, composers often published their compositions, saying that the music could be played or sung by various instruments. For example, when [[England|English]] composers published [[madrigal]]s in the late [[16th century]] they often stated that they could be sung by singers or played on [[viol]]s (“apt for voices as for viols”). In the [[Classical music period]] a composer might publish a [[sonata]], stating that it could be played on the [[violin]] or [[flute]] or [[recorder]]. This helped to sell more copies, because violinists, flautists and recorder players might all want to buy the music. In a sense this is not really an arrangement, because no changes have been made to the music. However, when [[violin]] or [[cello]] music is arranged so that it can be played on a [[viola]], some changes may be necessary as the viola may be playing in a different [[tonality|key]], or some [[chord]]s may be more awkward the way they were originally written. This is an arrangement. A popular piece such as ''The Flight of the Bumble Bee'' by [[Rimsky-Korsakov]] can be played by almost any melodic instrument: [[violin]], [[xylophone]], [[tuba]] etc. These are all arrangements. When a piece for choir and orchestra is printed for choir members to use, the orchestral part is printed on two [[stave]]s so that it can be played on a [[piano]] for [[rehearsal]]s. This is another kind of arrangement. In music history, many composers have made arrangements o
