Autograph musical quotation from the important twentieth-century composer, who has penned one measure from his 2005 work Freude for 2 harps, part of the cycle Klang. He has signed below with a heart (spelling "herz"-lichen Grüße in German) and identified the work in a postscript. Mounted together on a card with a clipped halftone photograph of the composer lecturing as a younger man, to an overall size of 4 x 6 inches (10.4 x 15 cm). Very fine.
