In his book on left-hand violin technique, Maestro Ruggiero Ricci addresses common problems in shifting by advocating the study of the glissando technique. He asserts that re-incorporating this technique will not only aid violinists in developing a better-trained ear, but also provide them with "shortcuts" to playing some of Paganini's most difficult passages.
Ricci introduces and compares old and new systems of playing to provide a context for the glissando system. He outlines a series of glissando scales that provides the student with a blueprint for developing additional glissando scales in other keys. He offers exercises designed to increase flexibility, ear training, coordination, and crawling technique and has included a DVD in which he demonstrates various bowing techniques.
