With Chiaroscuro, Willem Jeths has given voice to the boundaries between shadow and light, comparable to clair-obscur in the visual arts. Shorter and longer notes, repetitive, not much higher or lower, here and there a shining star that surprises with its loudness. The low final chord should sound until you can no longer hear it, or has disappeared into the darkness. And via that C sharp chord, there is a link within the 24preludia project with Bach's Prelude in C sharp major, BWV 848.
