After careful consideration I have withdrawn my membership from any formal music organizations. They take a considerable amount of time as well as money, and I don't feel they serve any benefits to my students. I don't find that today's students are interested in competitions, especially when they have to pay fees to enter and progress in additional levels. I would rather use a students' financial and time resources in performances that I have under my control.
I do actively participate in several online communities of piano teachers where I can receive further education, critique of repertoire and methods, and discuss other teaching issues with a worldwide community.
