Fiddle Magic
180 Technical Exercises for the Violin - By Sally O’Reilly:
Fiddle Magic is an extraordinary book of first and third position exercises that precisely isolate the myriad of problems intermediate and advanced violinists focus on:
Strengthening the left hand using the neglected fourth finger. Allowing time for depth of finger placement. Refining finger motion. Hearing high-low contrast. Developing flexibility and independence of finger placement. Concentrating on "high thirds" in major keys and "low thirds" in minor keys. Executing accurate shifts from first to third position.
