The highness or lowness of a sound is the

• pitch
• loudness
• vibration
• resonance

If you tie a string around a doorknob, pull on the string slowly, and keep plucking it with your finger as you pull, what happens to the pitch?

• As you tighten the string, the pitch gets lower
• The pitch stays the same
• As you tighten the string, the pitch gets higher
• You can't tell unless you try it
