The Suzuki method first came to the the United States in the late 1960s, and its official organization, the Suzuki Association of the Americas, was formed in 1972. As it existed in its early years, its proponents believed that all children could learn to play the violin if started at an early age, and that the learning process occurs through two primary mechanisms. The first is imitation, primarily imitation of the teacher. The second is group learning, consisting of group lessons and group performances. The suzuki books were put together for two primary reasons. First, to offer a structured program of pieces of increasing difficulty to use with each student over many years of their development; and second, to facilitate group learning by keeping everybody “on the same page” and able to play the same pieces together.
