Question

How does the sound change in a string instrument with the following changes:
1. Length of string increases
2. Thickness increases
3. Strings are struck harder
4. Strings are stretched​

Answer 1

Answer:

1. Length of string increases

Explanation:

When the length of a string is changed, it will vibrate with a different frequency. Shorter strings have higher frequency and therefore higher pitch. When a musician presses her finger on a string, she shortens its length.

Answer 2

Answer:

1. Length of string increases

Explanation:

• When a string's length is adjusted, it vibrates at a different frequency. Strings with a shorter length have a greater frequency and, as a result, a higher pitch. A musician shortens the length of a string by pressing her finger on it.

• Longer strings vibrate more slowly and produce lower-pitched sounds than shorter strings.

• To produce different pitches, instruments like the guitar and violin utilize the fingers to stretch or reduce the lengths of strings.
