I still think that creating art means taking a material (be it sound, color, stone, words, your body) and shape it into an adequate and significant form (adequate to both the material and the significance; to be more specific - let a sound take its time, a color take its space, use words to transcend themselves - poetry - ...and let the form make the state and the way of functioning of your mind apparent...).
I might just add that for this reason, serial and chance procedures (in musical composition) are only worth to be used to create some basic materials; nothing will spare us to make our own choice, take our own decision, and the responsability for the work. bernhard günter
