 Both of these intervals are associated with lament and funeral topics.Lutosławski initially treats the row canonically, answering this "dux" with a "comes" in the second cello, whose time interval is one beat (half-note, minim) and pitch interval is six half-steps (semitones) higher.This section features a technique that Lutosławski would later call "chain form," which also occurs in his "Passacaglia" from his Concerto for Orchestra.
