Pitch Pipes

The pitch pipe consists of one tube or several tubes with built-in penetrating reeds, or sound chambers with built-in reeds, which can be played by blowing into them. It is not intended for making music. It is used to set the pitch when tuning instruments. There are chromatic pitch pipes with twelve tones, those with only as many tones as the instrument to be tuned has strings, usually four or six tones, or even with only one tone for the alternative use of a tuning fork.
