And a much earlier take on the idea from the last post – "harmonizing" alien musical/graphic elements...
This is the one of the first pieces I used that sort of notation in and it is based on music from my solo piano piece Wilderness and Self-Sufficiency (Book takes the idea further but is not based on Wilderness). In The Beginning of Weight the pianist is asked to interpret this superimposed notation in relation to the meter, but is not instructed to perform the pitch material in any particular way. My hope is that different pianists will have different reactions to the illegibility.
Movses Pogosian (vln), Jean Kopperud (bass clar), Jacob Greenberg (pno). This is a recording of an informal reading, but I still think they played the hell out of the piece! MP3 and JPGs of the score below...
