"The Power of Film Music" by Guoyi Liu offers an in-depth analysis of the emotional power of film music and its influence on the viewer's experience. This academic book examines how filmmakers can control the emotions of the audience through the interplay of image, music, and editing. Liu uses Sergei Eisenstein's film theory as a foundation to illuminate the musical and cinematic elements in Bernardo Bertolucci's masterpiece "The Last Emperor." Through this analysis, new perspectives on Eisenstein's montage theory are opened up, demonstrating how music from artists like David Byrne, Ryuichi Sakamoto, and Cong Su significantly supports the film's narrative and emotions. This book is a valuable resource for anyone interested in the connection between music and film and who wants to understand the mechanisms behind the emotional impact of film music.
