In the picture
- Violin strings and bow: friction makes the strings vibrate, and the wooden body carries the sound.
- Clarinet reed and air column: a vibrating reed and the tube’s air column shape the tone.
- Trumpet mouthpiece and brass tube: buzzing lips and the metal tube shape the tone.
- Timpani drumhead: a stretched skin struck by a mallet vibrates and is tuned by tension.
Examples
- A guitar string vibrating after a pluck
- A recorder whistle made by blowing air
Key takeaways
- The vibrating material and its shape give each instrument family its own timbre.
- Sound starts with strings, air, lips, or a struck skin, then the instrument’s body colors it.
