Q1.
What happens if you use thinner or thicker rubber bands? Do they sound different?
Answer
Yes, they sound different. A thin band gives a high, sharp, thin sound. A thick band gives a low, deep, heavy sound.
| Band | How it shakes | The sound you hear |
|---|---|---|
| Thin band | Shakes very fast | High and sharp — like a small bell |
| Thick band | Shakes more slowly | Low and deep — like a big drum |
| Band pulled tight | Shakes faster | The note goes higher |
| Band left loose | Shakes slower | The note goes lower |
Why it happens: A thin band is light, so it shakes to and fro quickly. Fast shaking makes a high note. A thick band is heavier, so it shakes to and fro more slowly. Slow shaking makes a low note. Tightening a band has the same effect as making it thinner — it shakes faster and the note rises.
Look at a real instrument: On a sitar, a guitar or a tanpura the strings are not all the same. Some are thin and some are thick, and each gives a different note. Your box guitar works on exactly the same idea.
