1. Resonance Science of Music

2. Remember the Spring

3. The Result was OSCILLATORY MOTION Amplitude Time

4. Sprung

5. Friction Same Frequency Envelope Curve Energy Loss

6. Spring to Swing

7. Video – Bowling Ball

8. Video Driving the Spring

9. Resonance is a GENERAL phenomenon

10. Solid Objects All have their own modes of vibration. Each has its own resonant frequency. Musical Examples Cymbals – (very melodic!) Drum Bell Guitar &similar stringed instruments.

11. To remember -

12. Meet Ough

13. Where are we going? Vibration plate sand At RESONANCE, this thing makes a lot of noise. Else, not.

14. Other Frequencies

15. Video on Plates

16. Back to the old guitar …

17. Little String … BIG force

18. BIG Vibrations

19. Response vs Frequency Frequency Area of plate moving

20. What’s Happening?? It’s all about energy. String vibrates Gradually loses energy The plates begin to vibrate and produce a strong sound which is what we hear. The plates are vibrating in many modes at the same time. As the string loses energy, it stops supplying energy to the plates. The sound from the plates decrease with time as they run out of energy. Each mode has a different rate of energy loss.

21. Performer has some control.

22. Resonances of a guitar point.
