Changes in the conception of maqam theory between the 13th and 18th centuries

As is known, the modern "maqam theory" of Ottoman/Turkish music tradition is based on the concept of perde (standardized note names). In this study, we concentrated on the music-theoretical manuscripts written before the use of standardized note names, and we attempted to trace the evolution of maqam theory from the earliest period to the present time. In addition, we introduced new perspectives regarding the fundamental principle of abjad notation and the emergence of note names.
