Frigyes Sándor (1905-1979), violinist, teacher and conductor. His six-volume Violin tutor was published between 1949 and 1959, and has remained popular ever since. One reason for its popularity - in addition to its methodological concept ╩ may be the fact that from the very beginning learners are given high quality musical material on which to master the basic elements of violin playing. The musical material in the volumes was written specifically for this tutor by Pál Járdányi and Endre Szervánszky; apart from pieces designed for pedagogical purposes it includes a wealth of folk tunes (Hungarian and other European folk melodies) graded to suit each level of difficulty, and excerpts representing different periods in the history of music.
