Sevcik is essential for violin practice. It's usually divided into several volumes, but this collection is a critical collection, now difficult to obtain, that gathers the best of Sevcik's exercises. Although selections have been made, it's nearly 250 pages long and I believe it covers all the important aspects of Sevcik. It's more economical than buying multiple volumes. The book itself has no damage, writing, or markings, and is in like-new condition.
