Programme Note Per Nørgård LIBRO PER NOBUKO (1992)LIBRO PER NOBUKO (BOOK FOR NOBUKO) consists of two pieces written for Nobuko Imai the Japanese violist.Dedicated Nobuko Imai (1) and Bo [Vincens Steensen-Leth] (2) 1: Sonata 'The Secret Melody' (1a Prologue 1b Roaming 1c Singing 1d Playing 1e Epilogue) 2: Bofast (in English: Resident)The first (and longest) piece is a sonata in five movements called LA MELODIA SEGRETA (THE SECRET MELODY). The title is borrowed from a book by Trinh Xuan Thuan the Vietnamese astrophysicist. Of the mysterious and inexplicable order of the universe he writes: Nature sends us the notes of a music formed by a melody that will remain secretforever.The five movements of the sonata circumscribe a hidden melody: a clear melodic shape appears often enough but it soon reveals itself as being part of another superior melody - and so on. In this labyrinthine way the three middle movements framed by a short prologue and epilogue unfold different moods (roaming singing playing) in an eternal hide-and-seek of the melody (melodies).The second piece for Nobuko BOFAST (RESIDENT) is dedicated to Bo Vincens Steensen-Leth in gratitude of the many and selfless services he has rendered to the musical audiences at the locality of Langeland Denmark. The piece remains faithful to one single motif a 'resident' like Bo and his ancestors who have been residents at the manor house Steensgaard for over 400 years.Per Nørgård 1997
