Sound Study Guide

How do musical instruments produce sound?

• By pitching sounds

• Through air molecules

• Through vibrations

• By hiding wavelengths

What would best replace the number 2 on the chart?

• Making impact

• Mouth position

• Pushing air

• Vibrating strings

How does this instrument produce sound?

• Electrical currents are made when the bow and string meet and produce sound.

• The fusion with the strings makes the sound.

• As the bow goes across the strings, it causes vibrations in the violin.

• Wind energy is used to cause the vibrations between the bow and the string.
