Antonio Vivaldi : Gloria in D Major ( 1. "Gloria in excelsis Deo")

The Gloria in D Major, RV 589, combines concertante ritornello technique with liturgical text structure so closely that the individual sections appear less like isolated movements and more like varying perspectives on the same theme of jubilation.
It is also noteworthy that Vivaldi creates the strongest sonic contrasts not between the choir and the soloists, but within brief harmonic transitions, thereby ensuring that even familiar passages retain an unexpected fluidity.
