Why Music Moves Us
Follow a sound from a vibrating string, through waves and simple ratios, into the ear and the feelings music stirs.

- Amplitude is part of Sound wave Established
- Consonance depends on Harmonic ratio Contested

- Frequency is part of Sound wave Established
- Loudness depends on Amplitude Established
- Octave is a Harmonic ratio Established
- Auditory perception depends on Sound wave Established
- Pitch depends on Frequency Established
- Pitch is part of Auditory perception Established
- Harmonic ratio is derived from Frequency Established
- Tuning system is derived from Harmonic ratio Established
- Tuning system trades off with Consonance Supported

Activities & expected evidence
- Identify a missing link
A stronger sound wave is heard as louder — but the wave itself and loudness are not directly the same thing. Which property of the wave is the missing link?
Expected evidence: identified a missing link
- Explain the mechanism
Explain HOW simple frequency ratios (like 2:1 or 3:2) can make two notes sound consonant. Then note one reason it isn't purely mathematics.
Expected evidence: explained a relationship
- Predict an effect
Predict the ripple: what happens to the note if you double its frequency?
Expected evidence: predicted an effect
- Transfer to a new field
Equal-temperament tuning is a trade-off: give up perfect ratios in one key to play in every key. Describe a trade-off with the same shape in engineering, economics or everyday design.
Expected evidence: transferred a pattern
