VIBRATION
|
Answer |
In the second module on Vibration
(Spectrum & Timbre) it will be shown that a noisy
sound like a clap has a broadband
spectrum composed of a wide range of frequencies,
and therefore it activates many strings to respond
sympathetically.
You can try this out yourself any time you find a piano and hold down the sustain pedal (the one on the right). Try making various sounds (voice, instrument, other noises) and listen for the piano's ethereal response. |
