"Developing Virtuosity, Book 1" begins with open strings and basic notation, rhythms, and bowing skills. New notes, notation, and bowing skills are added in logical progression, reinforcing both right- and left-hand technique and developing the cognition for string performance. This book introduces students to: 1) the basic major and minor tetrachords on all four strings; 2) essential rhythmic notation from whole notes through eighth-note patterns; 3) left-hand techniques such as easily played double stops, left-hand pizzicato, and differentiating whole and half steps; and 4) bowing techniques, beginning with the detaché bow stroke and continuing with staccato, slurs, producing dynamics with the bow, lifting the bow, arco-to-pizzicato technique, and hooked and louré bow strokes.
