I found this nice article and free PDF to download from the Canadian Musician website. It's a series of articles on 'Tips for woodwind players' which includes everything from, embouchure to sound and rhythmic exercises. It even has an article on Carnatic saxophone which was quite a nice surprise. This is a really nice read so do check it out:
