PT Journal AU Ford, M TI Processes of spectralization: From Josquin's Missa "L'homme arme" Super Voces Musicales to Haas's Tria ex Uno SO Musicologica Olomucensia PY 2015 BP 7 EP 23 VL 22 IS 2 DI 10.5507/mo.2015.010 DE Georg Friedrich Haas; intertextuality; Josquin des Prez; musical borrowing; spectralism AB This article sheds new light on Georg Friedrich Haas's borrowing methods through an analysis of Tria ex Uno, which paraphrases a piece published half a millennium earlier: the Agnus Dei II from Josquin des Prez's Missa "L'homme arme" super voces musicales, which employs borrowing techniques itself. I demonstrate the transformation from the Agnus Dei II to Tria ex Uno by revealing Haas's specific spectral paradigms and techniques within a framework of Peter Burkholder's and Richard Beaudoin's work on musical borrowing. My study thus provides a means to understand the spectral treatment of existing music within the discourse on musical borrowing. ER
