A creative guide for the contemporary improvising violinist. The main aim is to add different material to the portfolio of the improvising violinist including new techniques, lines, and rhythmic patterns in harmonic settings as well as open settings. Classical skills are often missing in the Jazz Violin field; classical techniques are applied and brought into a Jazz context. Part I is a guide how to practice a scale and be able to use it in your improvisations. The concert etudes and concert pieces are a collection of technical material that can be used freely in improvisations, so it's not just exercises for practicing special techniques on the violin; it also shows how to use these in compositions and improvisational material. This book is not meant to be an all-inclusive guide or a pamphlet for the improvising string player. It is meant to open up the imagination of string players for new ways of playing their instrument and using these techniques in the context of solo or group improvisation.
