This book, authored by the late Princeton music scholar Harold Powers, discusses a single Indian r?ga called R?tigaula. R?tigaula?s pitch structure, conventions surrounding its performance, and its treatment in historical Indian music treatises are comprehensively described. Powers?s unique approach to theorizing r?ga examines r?ga structure and meaning in this monograph too, from the perspective of musical communication and discourse. From within this perspective, Powers shares his thoughts about music?s connection to language, and the relationship between r?ga expression and linguistic communication.
