Tuning Draw Reeds
-
1
Slide a single-edged razor blade under the reed.
-
2
Use a jeweler's three-squared file to scratch some metal from the flat, free end of the reed, moving in a diagonal line from either side of the reed to raise the pitch.

File just a little metal at a time, then check the pitch. Avoid shortening the reed too much.
-
4
Continue until the pitch is correct.
-
5
Etch or scratch metal off the arm of the reed near the rivet to lower the pitch.
-

Use the tip of the file for etching.

Use a dull, single-edged blade to support the reed while you are working on it.
Tuning Blow Reeds
-
1
Insert a small, flat screwdriver or a toothpick through the mouthpiece hole, pushing up the reed.
-
2
Use the flat side of the screwdriver or toothpick as a work surface for filing and etching.

Use your three-squared file to remove the metal.
