Tropus De profundis for
chamber ensemble 2013
Tropus De profundis’ for
chamber ensemble (2013) beginning impulse originates from Psalm 130 (De
profundis clamavi ad te, Domine). The composition’s suggestive text visualizes
as an upwards twisting spiral and its aural conception ended up being
cyclically repeated vibrations. I separated the whole timespan into twelve
sections, each of them has instrument pairs pulsing based on the prime number
proportions. As a second dimension I added random events that shape the
individual elements. The composition is a second trope of my earlier work Welt
gebaut ist (2007), the game of love and war (Andrus Kallastu, 2.10.2016).
