Genesis II: Canti strumentali op. 19 nr 2
The second part of the sonoristic cycle Genesis, titled Instrumental Songs, was composed for an ensemble of 15 instrumentalists: strings, percussion, winds, two pianos, mandolin and guitar. Genesis I: Elementi had struck the audience with the energy of three string instruments. Here, this energy is enhanced by the much richer palette of instrumental colours.
The sound in Instrumental Songs is incredibly powerful. The composer uses the loudest dynamics possible almost throughout the piece, presenting aggressive clusters and patches of sound colour performed by individual instruments as well as by their combinations. The piece is dominated by fast tempi and dense textures resulting from downward or upward shifts and overlaps of sound layers: clusters of string glissandi, tremolos, playing on open strings of mandolin and guitar, piano clusters and dry, repetitive percussion sounds, as well as individual high-register tones played by wind instruments. This phenomenal, elemental music calms down only toward the end, where the texture becomes simpler and the tempo slower, leading to a quiet conclusion.
