The title '…called dusk' quotes the last line of the prose fragment 'Lessness' by Samuel Beckett: 'Figment dawn dispeller of figments and the other called dusk'. As regards the compositional structure, the three movements of the work written 'in memoriam György Ligeti' are based on the tones of a Kaddish which, however, cannot literally be heard but, with the fingertips placed on the cello strings, generate artificial harmonics of totally different sequences of tones.
