After the Gloria, the high point of a mass setting is often the Sanctus and it is definitely so in this mass.
Here Taylor starts with more than a nod to NICAEA and it’s “Holy, Holy, Holy”, to establish a traditional base, before veering a little more nimbly through his very singable setting with more triplet action and a sustained chord before the resolution. The last line sounds very Christmassy.
He moves from the key of D in the Gloria to F for this and the Memorial Acclamations.
You can buy the mass at Willow in many forms.
Holy, Holy, Holy Lord God of hosts.
Heaven and earth are full of your glory.
Hosanna in the highest.
Blessed is he who comes in the name of the Lord.
Hosanna in the highest.
This is NICAEA – BTW you can actually sing the Sanctus to this tune:
