Query: ABCs of strings - the best series there is

I have been using this book as teaching material for around 2 years now and haven't looked back! The books in this series link fluently from one to the next, making learning and teaching seamless. This book is almost like three books in one - it consists of short studies, pieces - both familiar and new, and scales. Logical step by step progressions and notation is clear. The studies consist of new or challenging concepts which are then included in the piece to follow, allowing your practice to be thorough and time efficient. Each of the books maintain this structure. The best book I have ever used - HIGHLY recommended!
