In December 2015, Peter Eötvös composed his short work for violin solo which plays with hearing, perceiving and responding to musical structures. Inspired by a line from James Joyce's Ulysses, there is a call ('pure, throbbing and longindying'), as a siren-like sound, in the short theme of sometimes virtuoso variations. Very interesting with regard to the violin technique is a recurring droning noise of the tailpiece which structures the work's form.
