Suzuki ended up going to Europe as a young man to further his studies of the instrument. He was friends with Einstein, and studied violin with the foremost musicians of the day. When he returned to Japan he had an epiphany. All children learned their own languages effortlessly. Even dialects that were considered very difficult for outsiders, like the Osaka dialect, were mastered young children who grew up surrounded by their sounds. Suzuki applied that same notion to music, teaching violin to very young children, calling it talent education. The Suzuki method was introduced to the United States in the 1960s.
Technologically speaking, a lot has changed since then. Even since the 1970s and 1980s, when many present day Suzuki teachers who were themselves Suzuki students learned, technology has covered a lot of ground.
So today, I take notes on a computer, record new skills or special practice spots on my smart phone, and look up famous performers on YouTube for inspiration. My iTunes is full of play lists that say things like 'Winter Listening 2014.' I can search all Gavottes and do a little 'name that Gavotte' game in seconds. I use an online tuner nearly every day.
This winter when Charlotte was working on getting through all the bowing of the many variations of 'Twinkle Twinkle Little Star', nothing motivated her like a monkey chain. For every section of the song, she got to add a monkey, and that was more than enough motivation for her--for more than a week! It did not undermine her desire to play music, not at all. In fact, it provided valuable feedback, letting her know how much she had accomplished and giving her an idea of how much was left to go.
