Hailed as a leading innovator of visual montage, unique storytelling style, and ground-breaking cinematography, Jean-Luc Godard is a prominent pioneer in sculpting complex soundtracks altering the familiar relationship between sound and image, but his achievements in sound have been largely overlooked. Such a lacuna in the extensive research on Godard's work is unfortunate, as Godard's lifelong preoccupation of exploring self-reflexively all aspects of filmmaking particularly affects film music. With the novel approach of metafilm music, extrapolated from Jean-Luc Godard's oeuvre, this book not only closes up a crucial gap in Godard research, but also offers detailed analyses of the music as metafilm music in , , among other films and video productions. The innovative scholarly concept of metafilm music, enriching the burgeoning field of music in audio-visual media, describes how Godard thinks about film music with film music. This book thus provides a thorough examination of Godard's self-reflexive approach to film music which has resulted in a lifelong creation of multi-layered soundtracks pushing the envelope of film music and sound to the limit.
