By attending group class a parent will get to know other parents in the program and developed friendships. This can be true in your home studio or at a Suzuki Institute. A parent can also take home technical ideas that the teacher shares with other parents and students during the masterclass. You can use those ideas and practice strategies in your home practice.
Group class can also help parents get a focus for review. Review with a purpose behind it can be a great tool for home practice. Parents can use some of the points and ideas that were discussed in group class to help with review. You can apply the concepts of theory, history, character, meter, and other ideas from group class into your home practice.
