Holiday Concert 2017 - Parker's markings
Listening, with Parker's notes
Ceremony of Carols
There are many variances of pronunciation, phrasing, and voicing as there are recordings of this work, so I cannot recommend any one definitive recording. Here are a couple for your listening interest only-please do not learn/copy their diction or phrasing.
A highly produced version by a Swedish mixed choir. Don’t love their
chant procession, and diction weird in places, but impeccable blend.
A historic recording by a British cathedral treble choir.
