## Ready when they can

- Name the four families and give two instruments in each
- Describe how examples start sound: bowed or plucked strings, air blown across an edge, a vibrating reed, buzzing lips, or a struck or shaken object
- Use a stated playing action to explain an instrument's family, including cases where instruments share a material or pitch
- Use stated pipe lengths and end conditions to choose the lower lowest note in controlled comparisons

## Lesson: Four Families, Four Sounds

You have read about instruments joining a song. An orchestra groups instruments into four main families: strings, woodwind, brass and percussion. Use clues about how players start vibrations. Pitch, loudness or material alone does not tell you the family.

*(drawing: Each box matches an instrument to its family. This is not a playing order.)*

Violin and cello belong to strings. Players bow or pluck a string to start its vibration. The double bass usually plays lower parts than the cello. Their ranges overlap, so both instruments can play some of the same pitches.

Flute and clarinet are woodwind. A flute uses air blown across an edge. A clarinet uses a vibrating reed, a thin flexible strip. Even a metal flute is woodwind. Trumpet and trombone are brass. Players buzz their lips into a mouthpiece. Both families use vibrating air but start the sound differently.

Timpani and cymbals are percussion instruments that players strike. Other percussion instruments can be shaken or scraped. A struck metal cymbal belongs to percussion, not brass.

Pitch is how high or low a sound is. Vibrations are back-and-forth movements. Slower vibrations give lower pitches. For a fair comparison, change one feature and keep the others the same. Lengthening a vibrating string lowers its pitch when thickness and tension stay unchanged. For pipes of matching width and end conditions, at the same air temperature, a longer air column has a lower lowest note.

**Example.** Compare two ideal straight pipes of equal length and width, at the same air temperature. One is open at both ends; one is closed at one end. The closed pipe has the lower lowest note. Real instruments also have shaped tubes, holes or mouthpieces.

**Recap.** Use how the vibration starts to distinguish families. Compare pitch only with other relevant features held the same.
