If you aren’t reading Jennifer Cluff’s blog, I highly recommend surfing on over and spending a few hours: www.jennifercluff.com/blog/
Ms. Cluff’s blog gets my vote for being the most useful woodwind-related blog currently on the web, with long and in-depth posts about flute playing, including, sometimes, answers to readers’ questions. There is really excellent stuff here for beginners and very advanced flutists alike. I just finished reading her latest post, on excess movement in flute playing. Ms. Cluff’s posts are sporadic but always worthwhile, so subscribe to the RSS feed if you’re cool like that.
