Congrats, Tentaro on your book completion -- he finished the ABC's of Violin Book 4 on September 11.
This book reinforces the second position which could be challenging and somewhat boring. But he endured it and now is a second position master! I thought of going onto the next book to learn the 4th and 5th positions but instead, we will be just using "Position Etude" by Suzuki. Currently he is working on an etude from the famous Kayser book. Keep up a great work, Tentaro!
