Tonalization. By Shinichi Suzuki. Published by Summy-Birchard.
Tonalization includes all of Dr. Suzuki's basic ideas about tone. While it focuses on violin technique, it is conceptually relevant to the playing of any string instrument.
Dr. Suzuki questions why all vocalists vocalize every day to improve their voices, but instrumentalists do not do the same with their instruments. He believes that on any instrument, one needs to practice to make a more beautiful tone. He talks first about playing a beautiful, resonant tone with the bow while plucking the string with a finger. When a pizzicato is played, the resonance goes on for a long time. Students should listen to that resonance and play the same kind of clear beautiful sound. He talks about how to make a difference in the tone by using a different bow speed, how to practice to find the resonance point, how to change the weight of the arm on the bow to produce a different kind of tone, and how to change tone color.
