Homepage of Tim Reynish. He has emerged as one of the leading conductors of wind bands and wind ensembles in the world. His page is smart and insightful.
Great resource for many different percussion related topics, including playing techniques, musical issues/approaches, mallet/stick choice (the list goes on and on...)
This site is great in the general music classroom. There are short (three question) quizzes that go along with each podcast.You can play the podcast right from the website and view the accompanying text as well. There are also activities. Sign up with CFK as a teacher to receive additional lessons and activities.
