Demetrios Constantine Dounis was one of the most influential violin pedagogues of the twentieth century. This book is an in-depth study of Dounis' work and his art. The teacher of many of the great string players of our time, Dounis imparted to his students an organized and unified approach to violin technique. Chris A. Costantakos offers a complete introduction to the work of this man who valued the development of the mind and its observational capacities as one of the main steps in the mastery of any string instrument. This book is a necessary volume for the library of the beginning student as well as the experienced string player.
