I'm about a solid Suzuki book 3 player. It's most likely going to take me a year to get through book 4. What is covered in book 4 and is there another book you would recommend that is between these levels or at this level. I'm not too fond of classical music at the moment and would rather play another style at this level. I'm an adult with limited practice time so I stick to orchestra pieces, holiday music, country, pop hits, basic fiddle tunes, etc. I need a book that covers shifting positions and some slightly more advanced stuff.
I have not bought any of the Suzuki books yet, and I am at an earlier stage of learning to play the violin right now, but I have been buying a few different lesson books, by a few different authors. I have also been stocking up on lesson books for future needs.
One of the books I have is by Janice Tucker Rhoda, titled, "Complete Technique for Violin Book 1" (although I am not sure there is a book 2 yet).
Although I have not yet started studying this book, I have flipped through it, and you might, or might not, find it useful. The cover says that it has "400 exercises include 45 Musical Studies in Positions 1 through 5."
Right now, I am working mostly in her book, "The ABC's of Violin for the Absolute Beginner." This book is probably too basic for you, but I like the selection of tunes and exercises. I am nearly ready to move on to book 2, "The ABC's of Violin for the Intermediate Player," but I feel I still need to work on perfecting a few things in book 1 before I start the next book. I do not feel like an Intermediate player just yet.
Hope that helps you, or anyone interested.
