Creativity, by which something new, original, and valuable is formed, has positive connotations. This volume features essays on creative processes in technological invention, engineering design, architecture, music composition, improvisation, sound recording, authenticity in music, and computer music. They deal with significant present-day as well as with historical issues of creativity. They explore what creative processes in different domains have in common, to what extent cognitive science can shed light on them and how they can be modelled. Contrary to some approaches in creativity studies, the authors, if ever possible, try to avoid speculation and come to empirically valid conclusions.
