Gen Bryant‘s Sanctus from her Mass For Youth has matching melodic motifs with the Memorial Acclamations 1 and 3 and the Agnes Dei, which helps greatly from a learning perspective. There is mild syncopation and nice triplets to make things interesting.
Holy, Holy, Holy
Lord God of hosts.
Heaven and earth are full of your glory.
Hosanna in the highest. Hosanna in the highest.
Blessed is he who comes in the name of the Lord.
Hosanna in the highest.
