The guitar is transformed into a flute-like instrument where self-sustaining feedback causes the strings to vibrate on their own. | |
Sustain is traded back and forth between the same note on two different strings. (Listen with stereo!) | |
First a short phrase is played with damping by feedback control. Then for comparison, the phrase is repeated with no feedback control. | |
The introduction to Shining Star is played with damping, and some sustain is added at the end of the phrase. | |
Event-based control allows the spectral envelope to be precisely controlled. | |
Another example using event-based control sustain. | |
Tremolo is applied physically to the guitar string. | |
Vibrato is applied physically to the guitar string. |
NOTE: No new theory was used in the creation of these sound examples. This is a nice implementation that can be used in live performance.
