M.B. Istantanee II Cremona 2011 (Photo: Carlo Ferraroni) The work forms the second part of a trilogy I began composing in the fall of 2006 on a joint commission by both C.R.M. (Centro Ricerche Musicali) Rome and CEMAT for a concert within the framework of the celebration of the 10th anniversary of the latter Roman musical association. The aeolian object, a “sound sculpture”, is the same circular harp I employed in Istantanee I. Here, though, it is not the wind that modulates its sound but the activity of a solo performer. He makes its strings vibrate in three different ways coinciding with the three large time spans of the piece: in the 1st, by means of two jets of compressed air; the 2nd, by means of three small fans (two of them free-standing and the third fixed); and finally the 3rd, by buffing the strings with one’s breath. As I have already explained theoretically elsewhere (precisely in my dialogue “Aeolian Harps and other useless things”), the musical – that is temporal – development of the piece occurs freely within a formal strategy that emerges from Golden Section proportions based upon the duration of Istantanee I. |
