1000 Music Reading Studies for Violin includes all key signatures up to six sharps and flats, and several different time signatures. The exercises in each key start at an easy level and progress in difficulty with each new page. If you find the first few exercises are too difficult for your current skill level, I recommend working your way through my book and "200 Easy Sight Reading Studies for Violin and " first.In order to avoid the book having too many pages, the foreword, instructions, and preview are available for pdf download at Robert Anthony Publishing.
