The Routledge Handbook of Metal Music Composition: Evolution of Structure, Expression, and Production examines metal music composition as a distinct practice that combines a complex array of formal musical, expressive, and technological elements. Reaching beyond the limitations of applying common-practice theories of tonality to metal, this volume brings together a wide range of established and emerging scholars to address the building blocks of metal composition in the context of metal's subgenres and evolution over time. Together, the chapters provide a holistic theoretical framework for understanding the distinctive compositional features of metal. With contributions from an international group of experts, the handbook is organized into three parts around major themes: * Structures, including form, riff, harmony, rhythm, and meter * Instruments and voices, examining the role of the guitar, bass, drum kit, keyboards, other instruments, and vocal techniques and styles * Productions, addressing the role of gear, capturing, processing, and mixing technologies. The contributors examine and discuss these elements with the goal of building an understanding of metal music composition that can also function as a manual for composing metal music. Providing a comprehensive overview of the unique musical elements of metal, this handbook is an essential resource for scholars and students across popular music studies, musicology, creative music performance and composition, songwriting, and production studies, as well as for anyone interested in understanding metal from the perspective of composition.
