This piece was written in the wake of the trumpet concerto 'Eirene'. Both pieces were composed by Willi for the trumpeter Reinhold Friedrich who raves about the concerto: 'There is an inexplicable magic in this magnificent light/space work which gives both the audience and the musicians great inner pleasure.'
This magic, however, is created by ascetic rather than romantic and lavish means. Willi composed a series of brief musical actions, tone repetitions and short flitting snatches of melody. Wind players who are familiar with all kinds of playing techniques are given much room for their own artistic interpretation.
