Program Note:
“Wolke über Bäumen”, cloud above trees, is the name of a crayon drawing by Paul Klee: a sinuous, snakingly horizontal
nest of a line above a jagged, chaotic, but equally horizontal forest of sharp angles. What this private sketch has to do
with a detuned violin, strung with gut, with an interlocking series of canons in motu contrario, or with the concluding
Passagalia from Biber’s Rosenkranz-Sonaten isn’t entirely clear: but it’s something about simultaneous substrates, a series of tenuously balanced obstacles obstructing each others’ lines of sight.
