===Orchestration===
Once the music has been written, it must then be [[Orchestration#Film orchestration|arranged or orchestrated]] in order for the ensemble to be able to perform it. The nature and level of orchestration varies from project to project and composer to composer, but in its basic form the orchestrator's job is to take the [[Single-line (music)|single-line music]] written by the composer and "flesh it out" into instrument-specific sheet music for each member of the orchestra to perform.

Some composers like [[Ennio Morricone]] orchestrate their own scores themselves, without using an additional orchestrator. Some composers provide intricate details in how they want this to be accomplished and will provide the orchestrator with copious notes outlining which instruments are being asked to perform which notes, giving the orchestrator no personal creative input whatsoever beyond re-notating the music on different sheets of paper as appropriate. Other composers are less detailed, and will often ask orchestrators to "fill in the blanks", providing their own creative input into the makeup of the ensemble, ensuring that each instrument is capable of performing the music as written, and even allowing them to introduce performance techniques and flourishes to enhance the score. In many cases, time constraints determined by the film's post-production schedule dictate whether composers orchestrate their own scores, as it is often impossible for the composer to complete all the required tasks within the time frame allowed.

Over the years, several orchestrators have become linked to the work of one particular composer, often to the point where one will not work without the other.

Once the orchestration process has been completed, the sheet music is physically printed onto paper by one or more [[Copyist#Music copyists|music copyists]] and is ready for performance.
