These are wonderful books written for very young violinists. I like to use these books as a supplement to “Adventures in Violinland”
Book one teaches very simple rhythms and notes on A and D string
Book two teaches notes on the G and D string as well as more complex rhythms
I strongly believe that these books are a must for very young violinists. Children loves these books and the fact that they can color all the pages as they learn !
