Click on your instrument's Reed Doctor. The Reed Doctors are troubleshooters. They don't show you how to make reeds. When a reed plays up in rehearsal or concert, your Reed Doctor could get you out of trouble. Don't throw reeds away too soon.
All commercial reeds are, broadly speaking, blanks.
In any box of ten clarinet or sax reeds, for instance, only one or two will play with little trouble. Cane being a natural substance will vary whilst the machine's cut will not. If you know what to do, you can make the rest of your reeds work just as well. Commercial bassoon and oboe reeds are costly. You want to get the maximum use out of them.
