What is the total number of performers described for the 40-50 instrumentation?

• A. 30-40 performers
• B. 30-45 performers
• C. 40-50 performers
• D. 50-60 performers

Answer: (C)

Interpreting instrument-group labeling helps you determine the total for a section. When an instrumentation is described as 40-50 performers, the label tells you that the entire group assigned to that set of instruments should consist of forty to fifty players. To answer, you sum up the players listed for all instruments in that group and check whether the sum falls within that range. Here, the total described for the 40-50 instrumentation falls between forty and fifty players, which matches the label, so that is the correct total. The other ranges either require too few or too many players and do not align with the stated label.
