Editing Reed (mouthpiece) (section)

==Single reeds==
Single reeds are used on the mouthpieces of [[clarinet]]s and [[saxophone]]s. The back of the reed is flat and is placed against the mouthpiece. These reeds are roughly rectangular in shape and taper towards the thin tip, which is rounded to match the curve of the mouthpiece tip. All single reeds are shaped similarly but vary in size to fit each instrument's mouthpiece.

Reeds designed for the same instrument look roughly identical, but vary in thickness ("hardness" or "strength"). Hardness is generally measured on a scale of 1 through 5 from softest to hardest. This is not a standardized scale and reed strengths vary by manufacturer. The thickness of the tip and heel and the profile in between affect the sound and playability. Pieces of cane of different density or stiffness, even if cut with the same profile, will respond differently due to those differences.
