So, All Saints has historically just sung the Great Doxology in Tone 6 (that’s “Second Plagal Mode” for those of you out there who speak Byz) since time immemorial, and I am starting the long, slow process of incorporating the other seven modes into our liturgical practice. My understanding has always been that it goes with the Resurrectional mode of the week (an understanding reinforced by the OrthodoxWiki entry for the Great Doxology, which is clearly a critical source of no small import), but looking at the AOCNA liturgical guide (online, printed, and L.A. diocese version) it appears that they have it going with the Eothinon (hence being in Tone 5 this week rather than Tone 7). Looking at the Liturgikon, the “Five Pounder” (Divine Prayers and Services, Nassar), and the Antiochian little red service book, a rubric is not provided that resolves the question; in the Kazan Byzantine Project Matins book, the table of contents indicates that the Great Doxology is sung in the “tone of the day” but then the rubric in the music itself has it going with the Eothinon (first Eothinon, Tone 1, second Eothinon, Tone 2, etc.).
Can anybody clear up for me what’s happening here?
