Vibrations performance I.
materials needed: electric string instrument, amplifier, speaker, audience
to produce sound, physically apply the instrument to the speaker housing and turn up the volume until vibration feedback starts to occur.
when one string reaches its maximum amplitude of vibration, mute that string and allow another string to create feedback
after each string has been "played" experiment with the tuning pegs on the headstock to create different tones. first tune the instrument down as tuning the strings any tighter than standard tuning often results in broken strings.
please limit yourself from pressing down the string onto the frets or fingerboard as this is too close to the conventional way of playing string instruments.
feel free to use any effect/ loop pedals to create interesting sounds/ interactions
disclaimer: keeping your instrument fully un-tuned for any length of time after this performance is ill advised as the instruments neck may drift out of its proper alignment.
i played this piece for an audience and originally tried to manipulate the sound using string harmonics on the neck of the instrument (harmonics are when a player only partially presses on a string at specific frets of the neck of an instrument allowing both halves of the string to vibrate. see Jaco Pastorius' portrait of tracy) this form of manipulation of the instrument was unsuccessful because it did not change the tone of the vibration and it also did not mute the vibrating string either.
while performing i wished that i had a third hand arm. for my performance i routed the strong signal from an amplifier at max settings into a small speaker. the force of the extremely high gain signal made the speaker shake violently. i held that small speaker to the bridge of the instrument facing outwards.. so as i was saying about wishing i had a third hand: one hand was holding the speaker to the instrument and the other was managing the strings on the neck, i wanted a third hand to cup around the small speaker and manipulate the sound my moving my hand over the sound holes. this concept works similarly to how a musician with a talk box (see peter frampton or bon jovi's living on a prayer guitar riff) shapes the sound of their instrument with their mouth
