Knocking, Tapping and Rapping are terms to describe sounds as well as cultural practices that have important functions in a wide area ranging from everyday life to arts, religion, language and philosophy, communication and language. It became virulent recently in the political discussion about the «no-knock warrant» in the US.
But there seems to be more to the subject than that: from the use of knocking to test material to the literary topic of door-knocking, to the extensive use of knocking sounds in sound art and contemporary music. The sound of knocking, tapping and rapping inhabits and intervenes in multiple contexts.

For a two-day roundtable mini-symposium on the auditory phenomena ARS - CUPRAS has invited contributors from a variety of academic fields and professions as well as artistic contributions on the theme of knocking, tapping and rapping.

We would like to enable a multi-disciplinary exchange and hope to bring together a wide variety of approaches and views. And we also welcome contributions that approach the field of everyday sounds and their meaning under a different connotation.
