Office and Mass on Easter Day - Listening

Introit - (Proper)
This recording is completely monophonic.
The singers were all male.
I liked the texture of the piece; it seemed to speed up and slow down enough to keep me interested. The range of pitch had the same large dynamic, which is refreshing for sometimes more monotonous chants that I've heard in the past.
The first half is neumatic and melismatic, where later in the piece where it seems to speed up and gain a more positive energy, it becomes syllabic.

Kyrie - (Ordinary)
This seems to be a call and response.
This is significantly more melismatic.
It seems to be more metered. Most of the phrases are a wedge (>) in that they always start higher in pitch than they end.

Gloria
This one, probably for obvious reasons, seems to be the happiest sounding thus far. Another call and response.

Agnus Dei - Ordinary (on Easter)
It's interesting to me that there are repeated triad-sounding motives at the end of the phrases.

Agnus Dei (2)
Seems as though it's nearly a pedal at the beginning (on F). This is a more beautiful rendition. No matter where the phrases go, it seems to find its way back to the same pitch (F). This is another call and response. The Agnus Dei recordings seem to be shorter.

Agnus Dei (2) (on Christmas)
This one started with a phrase ending in a leading tone and resolution. Seems almost tonal, like the second Agnus Dei.
