Chord-aggregate

A chord comprising several overlapping simple chords. A quality characteristic of Lutosławski’s harmonics in his mature works. The composer liked to divide various chords comprising a chord-aggregate between various registers or harmonic bands, in order to produce the required sound quality in the instrument groups. Following the principle of “there should be no unimportant sounds in music”, Lutosławski always used these ideas with concrete sounds in mind.
