It was a coincidence that both Pedro and myself were already
making use of fans for different purposes, Pedro was allready
running some tests with fans to excite guitar strings to vibrate, we
took these explorations further trying with different fans and with
different ways to position them in order to get the best sonic result.
We ended up choosing to use 220v 12cm axial fans attached to the
first fret of the guitars arms and the wind blowing in the guitars
body's direction, we tuned all the guitars in specific frequencies that
are related to the specific rotation frequency of each fan making
use of the sympathetic resonance phenomenon in order to get the
loudest string vibration possible captured by the pickups. Although
this process rendered audible the guitar's sound it was captured by
the pickups on a very low volume, we were then using a mixer to
plug all the guitars in and then connecting the mixer's output to a
guitar amplifier, this way we could bring each guitar's volume as
higher as we could and then bringing each one very close to the
feedback threshold. The soundscape created being somehow
instable in feedback terms could be affected by the movement of
the spectators in the room bringing the feedback closer to being
heard.
