This is a new rendition of the original ``Freddie the Friedlander'' for physical model of the bowed string plus artificial performer. This version adds visuals and color in an attempt to image-by-synesthesia fabrication. This is the trailer of the sound installation
Sound sources result of bowing a string allow for continuous input of gestural energy to hold a sound product of vibrations given by friction between a bow and a string. With high static friction, the bow sticks to the string for a moment, drags the string along until it bounces back (reflecting) to its original position, thus generating vibrations in a process known as Helmholtz Motion.
F the F is a multiphonic piece meant to be viewed and listened on a Dolby surround audio system. This piece was composed on Common Music, Common Lisp Music and other open source software for visuals on a Linux system.
