What does orchestra score mean?

An orchestral score is a type of musical notation that represents the arrangement of musical notes and other musical symbols used to conduct an orchestra or other large musical ensemble. It provides a detailed roadmap of the entire musical composition, including the parts for each instrument and vocal section. The score contains information about the timing, dynamics, tempo, and other musical instructions that guide the musicians during a performance. It is typically presented on a large sheet of paper or multiple sheets bound together, and is read by the conductor while leading the orchestra.
