There's No Sound In My Head(19:44) A documentary by Robert Arnold about Mark Applebaum's Metaphysics of Notation. Although this film is not directly related to the field of acoustic-ecology it is interesting in that it is about the graphic representation and interpretation of sound. According to Wikipedia, "Graphic notation is the representation of music through the use of visual symbols outside the realm of traditional music notion Graphic notation evolved in the 1950s, and it is often used in combination with traditional music notation.Composers often rely on graphic notation in experimental music, where standard musical notation can be ineffective." This graphic mapping seems similar to that of soundscape documentation through graphic representation. Source: Vimeo
