Instrumentation, also called orchestration, in music, arrangement or composition for instruments. Most authorities make little distinction between the words instrumentation and orchestration. Both deal with musical instruments and their capabilities of producing various timbres or colors. Orchestration is somewhat the narrower term since it is frequently used to describe the art of instrumentation as related to the symphony orchestra. Instrumentation, therefore, is the art of combining instruments in any sort of musical composition, including such diverse elements as the numerous combinations used in chamber groups, jazz bands, rock ensembles, ensembles employing chorus, symphonic bands, and, of course, the symphony orchestra. In Lay school, we are teaching Guitar, Keyboard, and Band.
