Orchestral part

from Wikipedia, the free encyclopedia

An orchestral part is a sheet of music or music book for a musical instrument in the orchestra , that his voice has, so all of this instrument in a polyphonic work like an opera or a symphony has to play. The musical performance material of an orchestral work consists of the score (in which all instruments are notated one below the other) for the conductor and the orchestral parts for the instrumentalists. The vocal groups with choirs, as is usually the case with the string instruments, play from the same duplicated voice, which is available once per music stand. When it comes to winds, everyone usually has their own orchestral part.

Until the end of the 20th century, copyists wrote out the orchestral parts by hand from the score, which was a major cost factor for music publishers in the production of materials, but which still entitles them to high material rental fees. For this reason, orchestral parts of many works are often only available on loan to this day.

Today's music notation programs offer numerous aids for the automated production of orchestral parts. The interior of the turning points for turning in the appropriate time and the cues to facilitate operations after longer breaks instead require some orchestral experience and can not be automated.
