Quizplus · Accepted Answer

The pitch of a sound is determined by the frequency of the vibrations, and the frequency is directly related to the length of the vibrating element. A shorter element produces higher frequency vibrations and a higher pitch sound, while a longer element produces lower frequency vibrations and a lower pitch sound.
