op. 7
The piano piece Invocation 52, op. 7 was my first compositional - somewhat unconventional - exploration of Arnold Schönberg's row technique. Bitonal harmonies, which form a 12-tone total, are juxtaposed with a resolution into lines, each of which is supported by sustained notes and varied rhythmically. The formal framework is formed by two "calls" that are identical in terms of tonal material, each ending with the note e flat' , finally fading away in ppp.
