Jeffrey Rowell-Reverberant Art
1)Selectable Spring Reverb Two soundboards with high tension springs between them with a controllable damper on each spring. One sound is input on one side and picked up on the other with variable amounts of reverb.
2)Variable Reverb Room A room with a microphone and moveable walls/ceiling which would analyze the pitch of voices within it and attempt to change the shape of the room to highlight harmonics in the voice.
4)Coupled Pendulum Pickups A pair of guitar pickups are mounted on a set of coupled pendulums, and then set in front of two strings vibrating at close but different frequencies. The output of the pickups is then fed into a loudspeaker mounted close behind the system for feedback.
