A piece created from almost nothing - from two or three notes. The struck chord punctuates the piece, like the evenements of a lifetime. And the music unfolds according to a logical sequence: 1+1+2+2+3+3+4+4+5+5=30. Thirty bars in the blink of an eye. Alternating group by group, balance and chaos, calm and movement, linear and fragmented. From the very title the piece is characterised by its duality.
