Question

Explain the two ways by which the pitch of the sound generated by a stretched string can be changed. 

Answer 1

1. A string vibrates at a specific fundamental frequency. It is possible to make pitches with multiple frequencies with the same string.
2. The length and diameter of the string determine its frequency.
3. Changing the length of a string causes it to vibrate at a different frequency. Shorter strings have a greater frequency, which leads to a higher pitch.
4. When a musician presses her finger against a string, she reduces its length. The more fingers she puts to the string, the shorter it becomes, and the higher the pitch.
   Thick strings with a big diameter vibrate slower and at a lower frequency than thin ones.
