This document provides an introduction to using sound and music in film. It defines diegetic and non-diegetic sounds and gives examples of each. Diegetic sounds are part of the narrative world of the film, while non-diegetic sounds enhance the narrative but are not part of the fictional world. The document encourages experimenting with foley, sound effects, film scores and beat mapping to add diegetic and non-diegetic sounds to a film clip in Logic Pro X. It provides links for additional resources on sound design and music for film.
