It is truly amazing what is both hidden but then revealed about scripture within chant. Often, we tend to look for such things only in the liturgical “seasons”, forgetting that Tempus Ordinario – “Ordered Time” – is in fact the longest of those seasons.
We find ourselves now entering the tenth week of Ordinary Time with the themes of the chant having to do with God’s protection, most beautifully said in the opening line of the introit “Dominus Illuminatio” – “The Lord is my light and my salvation; of whom shall I be afraid?” (Psalm 26:1-3) And it is this chant which sets the stage for the focus of this week’s blog – Alleluia, Deus, qui sedes super thronum – “Alleluia: The Lord who sits upon His throne.”
This Alleluia, a mode VII tune, opens briefly with a mode VIII intonation, but then quickly races further upward to the pitches re and fa, giving a sense of the mode VII intonation.This is intriguing, though it’s not particularly unusual as these two modes are closely related, as these sounds create a sense of “lift” before coming to rest on sol. The verse continues this same “lift” with both exact melodic repetition of the opening and then variation, climaxing in a melisma on the word thronum – “throne” – of no less than 74 notes! Equally astounding to its length is its range – a full 10th from bottom fa to upper la. There is no doubt remaining that this throne must belong to God who resides in height, depth, and everywhere in between!
It is fascinating to note that in this entire Alleluia, there are 95 notes prior to the referenced melisma and 103 pitches following. From just that quick glance, the melodic structure of the piece clarifies, revealing to the listener a most important symbol of the “most High” God. The final phrases are a melodic extension of the opening Alleluia Jubilus, carrying the text that it is this same God who is both just and the refuge of the poor. These phrases constitute one the longest and gentlest melodic descents in the chant repertoire, with no sudden turns – somewhat like a leaf gently falling to the ground on a cushion of undisturbed air. What better way to audibly reveal the justice and mercy of God.
