Things You'll Need
Instructions
Insert the blade of a flat-head screwdriver into the lips of the mouthpiece and gently twist the blade about 1/8 turn to slightly spread the lips.
Grasp the reed with a pair of tweezers. According to the manufacturer, the end of the flat reed should be 1/8 inch from the lips of the mouthpiece.
Pull the reed toward you slightly to lower the pitch of the call. Push the reed away from the mouthpiece slightly to raise the pitch of the call.
Gently say "fuu" and "all" into the mouthpiece to simulate a crow alert or assembly call.
