Il Guido is closely related to Guido D'Arezzo's Ut queant laxis - though admitedly as if heardthrough the prism of many centuries. I took the intervals and contours of each of the phrases of this ancient hymn and opened them up to new possibilities. The live electronics allow for these explorations to sound and re-sound creating a sonic palimpsest in real time. Each time that it is performed, a new palimpsest will be created. For more than a quarter of a century Roberto Fabbriciani has been my personal Guido D'Arezzo. 2024 marks the centenary of the birth of Luigi Nono and was composed at Roberto Fabbriciani's invitation. Il Guido is dedicated with profound affection to my dear, generous friend Roberto Fabbriciani - flute virtuoso, maestro and a great friend.
