The default setting of the Exaposteilarion of Great and Holy Friday for those in the Russian tradition seems to be one of the Kievan chant settings, so why am I adding my voice to the din? Well, for years I have thought about composing a full-choir companion setting to my own treble-trio version. Then a couple weeks ago I realized that in fact the Kievan chant setting would work just fine with it. So here’s a version in the same key as my trio, presented with the idea that the full choir sings the Kievan version, the trio is performed for the second repetition, and then the Kievan version is sung for the third iteration.
This harmonization is based on Vladimir Morosan's setting of one of the other hymns of Great Week to the same melody, “When the glorious disciples” (the apolytikion of Great and Holy Thursday).
