Occasionally, I get asked questions about what type of soprano to get if you're just starting out. Here's one I recently received from pianist D C DowDell.

As far as mouthpieces, I would start with either a Selmer, Vandoren, or Bari--they, too, are the most consistent. Just make sure the tip opening is not too wide. Reeds could be anything, as long as they are of moderate strength. Ones that are too soft and too hard makes the pitch go sharp. I play RW reeds, which might be good for beginners, since they come in micro-sizes, which enables you to find something to tailor fit your needs. But reeds can be non-entity in the beginning stages. Find something that will vibrate and get it on with it, I always say. Right now, the focus should be getting a sound that can be controlled.
