Length Open Pipe Instrument Affect Higher Pitch. And it produces different notes (that is, notes of different pitch) by setting the air vibrating in pipes of different lengths: E, a, d, g, b, and e (an octave higher).

Shorter strings have higher frequency and therefore higher pitch. The diameter of the pipe or tubing does. The faster a string, wire, or air in a tube vibrates, the.
