Although since 1962 his works had been written on the basis of a system of tables, in this requiem the composer opted for traditional tonal and harmonic means. Despite a clear simplification of the means of expression, Mycielski was happy with the result achieved: “I’m moved by two modulations. Music should be written in SUCH a manner. ‘On the spot’” (Konstancin, 10 December 1983), “I think I may have found the truth [here]” (Konstancin, 13/14 December 1983).
The composition was premiered on 5 August 1989 in Wiśniowa by the “Melodia” Singing Society Mixed Choir in Mielec (chorus master – Jerzy Kopcewicz) and “Echo” Male Choir of the Culture Centre in Wiśniowa (chorus master – Andrzej Szypuła), with Ewa Grzebień on the organ.
