Suzuki Institutes around the world run workshops, camps and concerts in their areas. Sometimes, membership to your local Suzuki Institute will enable you to attend events even outside your local area. Parents usually attend all events and lessons with their children, even teenagers.
Before attending Suzuki events please check in with me because I want to ensure that you are sufficiently prepared to get the most out of the experience. I will check that you have all pieces up to your current working piece memorised (or at least your most recent book), and that you are actively working on posture and tone as well as learning notes.
New Zealand Events
To attend Suzuki events in New Zealand you can join the New Zealand Suzuki Institute. You'll find a list of local events on their site. The following notes are from my experience of events in the South Island but they are probably quite similar to how events run in other places.
Concerts - usually held on a week-end afternoon. Often involve a small cost to cover room hire. Performers are expected to announce their name and the piece they are playing, then to bow to the audience. They always perform from memory and bow again after playing. Violin players then thank the accompanist, if there was one. Usually there is no dress code but sometimes performers are asked to wear concert dress (black-and-white). In most concerts it is considered quite acceptable for a parent to go up onto the stage to support a hesitant small child.
Workshops and camps - The difference between these is that accommodation is provided as part of a camp whereas no accommodation is provided for a workshop. Both events usually run for a few days in a row. They usually start with an informal "play-in" where all the children play some pieces together in casual dress. They usually finish with a "play-out" concert, which is more formal with children wearing black-and-white. Most lessons start and end with the child and teacher bowing to each other.
In South Island events children usually attend three 1-hour classes each day. The three classes are:
a masterclass where a group of children and parents sit in the room together. Each child takes a turn at having a short lesson with the teacher while the others watch and their parent takes notes.
a group class where a group of children play pieces together (from memory)
the third class might be "music enrichment" (music-related games) or playing in an orchestra or doing fiddling.
Most children attend all 3 classes each day but preschoolers who do not yet learn any instrument can often attend just music enrichment and slightly older children (aged about 3 to 5 yrs) who are only learning the twinkles can attend just two classes (music enrichment and a group class).
Some workshops/camps involve each child playing an individual concert (see the notes on concerts above).
