This introduction to the Cambridge Companion to the Electric Guitar offers a concise synopsis of the dominant narrative surrounding the instrument, and establishes the ways in which the current collection seeks to expand the existing framework for considering the electric guitar’s history and cultural impact. It also discusses the provisional development of “guitar studies” as an academic field, highlighting trends in conferences, journalistic and special interest publications, and discussions surrounding music technology, the electric guitar industry, and socio-demographic issues such as gender, race, and age. While electric guitar scholarship has made significant progress, it has not fully established itself as a distinct field. Currently, there is no dedicated journal or professional organization for researchers in this area. “Guitar studies” may not yet have come to fruition, but its foundation is being laid, to which this Cambridge Companion intends to contribute.
