Being the first ever scales and exercise book published for Armenian traditional and extended range duduk (invented by Georgy Minasyan himself) Duduk Virtuoso has been written having the future of duduk in mind. While the traditional duduk has limited playing range of around one octave, extended range duduk allows performance across two octaves and in all twelve keys, significantly increasing the instrument's repertoire. Therefore the book has dual purpose: to help aspiring musicians to increase playing proficiency of the traditional instrument, and to bring to light the full potential of the instrument through mastering the improved instrument. The material, therefore, is designed in a way that will help both curious students and professional performers to further develop the flexibility and agility in all the fingers across the scales previously unfamiliar to traditional duduk. The scales and exercises are sequenced from easy to complex, so that each successive exercise increases the performance challenge and builds the mastery.
