In the picture
- Violin and bow: the bow rubs the strings and makes them vibrate.
- Flute mouth hole: a stream of air splits and sets the air inside vibrating.
- Trumpet mouthpiece: buzzing lips send vibrations down the brass tube.
- Timpani head: a struck skin vibrates over a tuned bowl.
Examples
- A guitar string hums when you pluck it.
- A drum skin shakes when you hit it.
Key takeaways
- Orchestra families are grouped by how they make sound.
- Vibrating strings, air, lips, and skins all create musical notes.
