Scot Gresham-Lancaster writes of the Octohedral Harp —
“This controller has gone through several versions and prototypes but all the investigations share the common thread: investigating a three dimensional relationship between solid struts and strings under tension with electronic sensors detecting proximity and frequencies.
This instrument has 72 strings that are tuned to a specific set of just intonations based on the physical geomety of the 3 axis (xyz) that they a running on. 6 strings on each quadrant of all 3 axis = 72. There would not be 72 distinct frequencies on the harp but rather a total of 40 distinct frequencies present. those 40 distinct frequencies are detectable with some ease by a computer, The use of commercially available hex guitar pickups insures some isolation of these frequencies at each bridge. The instrument is played with the techniques of most harps, but since each of the strings is a seperate capacitance antenna they each of the 6 strings per axis acts as a distance sensor.”
