Detailed explanation-1: -Woodwind pitch depends on the volume of air that is vibrating. A larger volume vibrates more slowly, for lower pitch; a smaller volume vibrates more quickly, for a higher pitch. For most woodwinds, the player changes pitch by opening and closing holes along the instrument’s length.
Detailed explanation-2: -The air gets split by the edge causing vibrations, like when you blow across the edge of a bottle. The edge may be at the mouthpiece or further inside the mouthpiece. In reed instruments the sounds or vibrations are made when the air travels across a thin piece of wood called a reed. The reed vibrates making the sound.
Detailed explanation-3: -The air inside the pipes of a wind instrument vibrates. The tubing in a wind instrument confines the motion of the air inside it-the air particles must wiggle parallel to the walls of the pipe. The result is a longitudinal standing wave in the air column inside the pipe.
