Generates the actual sheets of music used by the players (Music Preparation). This person will receive the orchestral scores from the orchestrator and create separate parts for the individual instruments. May also create the rehearsal piano and/or piano-conductor parts. Traditionally done in pen and ink, now often done on computer.
A copyist is a person who makes written copies. The term's modern use is almost entirely confined to music copyists, who are employed by the music industry to produce parts for individual musicians from an orchestral score or composer's manuscript. In the past, copyists worked by hand, though today the work is generally done using one of a number of proprietary specialist software packages (one of which is called Copyist); each approach requires a significant understanding of musical notation, music theory, and strong attention to detail.
