Borodin's Requiem for Solo tenor, Men's chorus and Orchestra,
is quite a short piece and has very little to do with any attempt at a full-scale requiem. In fact it originated in a short polka in which Borodin incorporated the nursery rhyme Tati-Tati (also known as Chopsticks). Other members of the "Mighty Handful" also wrote short pieces using this children's song, so that Borodin later completed two other pieces also incorporating Tati-Tati, Requiem and March. Borodin apparently mentioned the words "Requiem aeternam dona eis, Domine, et lux perpetua luceat eis" seemingly meant for tenor and male voice chorus. Why he did so, we are not told. Leopold Stokowski made an arrangement of it including tenor and male voices. As might be expected, Stokowski's arrangement is quite effective though, as usual, he tended to make it sound larger than life. A curiosity, though well worth the occasional hearing.
