Sound & Music: Frequency & Pitch
📋 What it is
Higher frequency means higher pitch; instruments make notes by controlling how fast things vibrate.
🗣️ Coach says
Music is organised vibration. The faster something vibrates (higher frequency), the higher the pitch we hear. Shorter or tighter strings, smaller drums and shorter air columns vibrate faster and sound higher; longer/looser ones sound lower. Musicians tune by changing frequency.
🧠 Memory hook
Faster vibration = higher pitch. Short/tight/small → high · long/loose/big → low.
😂 Giggle
Why was the prism the life of the party?
It really knew how to break things up into a spectrum!
😲 Whoa!
A tiny mosquito’s whine is high-pitched because its wings beat hundreds of times a second; a huge foghorn is low because it vibrates slowly.
✅ Quick check: Why does a thin, tight guitar string sound higher than a thick, loose one?
Say your answer out loud first — then reveal.
It vibrates faster (higher frequency), and higher frequency means higher pitch.
Pitch rises with vibration frequency.
🧪 Try it! (2 minutes)
Stretch a rubber band tight and pluck it, then loosen it — hear the pitch drop as it vibrates slower.
