Phenomena associated with the voice have very diverse possibilities of interpretation and consideration. What emanates from the voice and addresses someone exposes itself to the fragility of the moment and thus also to failure. Call sounds in this sense stand not only for composed material, but also for lamentations, signals, shouts of joy, or in poetry introduced emphases of an important address. In my understanding, the call, or the call sound as an archaic and even in the animal world existing means of communication also resonates with a timelessness and cultural universality, which fascinates me deeply: we can all hear a call sound as such and yet always have an individually and culturally distinct feeling and understanding for it.
