My youngest son is learning the violin through the suzuki method. Parents are very involved and are expected to have some basic strings knowledge so that they can help/support their youngster with learning the instrument. They also like you to develop a musical environment at home in order to keep the kids enthusiastic about their learning.
The suzuki method favours group learning as well as individual lessons - these groups sessions are fun and designed to encourage youngsters to pick up on each others enthusiasm.
I think that 'Twinkle, twinkle, little star' must be very important because my youngster has been learning this since he first started a few weeks ago
