The Suzuki Method(R) of Talent Education is based on Shinichi Suzuki's view that every child is born with ability, and that people are the product of their environment. According to Shinichi Suzuki, a world-renowned violinist and teacher, the greatest joy an adult can know comes from developing a child's potential so he/she can express all that is harmonious and best in human beings. Students are taught using the "mother-tongue" approach. Each series of books for a particular instrument in the Suzuki Method is considered a Suzuki music school, such as the Suzuki Violin School. Suzuki lessons are generally given in a private studio setting with additional group lessons. The student listens to the recordings and works with their Suzuki violin teacher to develop their potential as a musician and as a person. This Suzuki Book & CD is integral for Suzuki violin lessons. This revised edition of the Suzuki Violin School, Volume 3 features: * Revised editing of pieces, including bowings and fingerings * Additional exercises, some from Shinichi Suzuki, plus additional insight and suggestions for teachers * Text in English, French, Spanish, and German. * Musical notation guide * Fingerboard position * CD with recordings by William Preucil Jr., accompanied by Linda Perry, as well as piano accompaniments recorded alone.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive coverage of what the Suzuki approach embodies, this book should be considered a requirement in the home of every piano teacher and student. Eight of the 14 chapters lay the foundation for understanding Suzuki's Mother Tongue Approach, its procedures and its benefits. The authors have given their ideas of what it takes to be a Suzuki teacher, how to structure an effective lesson, what to cover in those first lessons and how to do it. Using more than 400 musical examples, the teaching points and the interpretation of the seven volumes of music are presented. In addition, some alternate fingerings are suggested and places where the Suzuki edition departs from the original edition are noted.

Book excerpt: Dr. Suzuki questioned why all vocalists vocalize every day to improve their voices, but instrumentalists do not do so every day with their instruments. He believes that on any instrument, one needs to practice to make a more beautiful tone. First he talks 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. This book includes all of Dr. Suzuki's basic ideas about tone.
