One of the YouTube channels I keep an eye is that run by Enrique Guerrero who when he's not lecturing on the topic is busily engaged in uploading videos of Viceregal and Colonial music such as this one. This video is the first verse of Quem terra pontus sidera [aethera] by Manuel Arenzana who was maestro de capilla at Puebla Cathedral from 1792 to 1821. I suppose if you wanted evidence thatthe choir at Puebla was well-financed Arenzana's liturgical music is it – every single liturgical piece he ever composed is not only very large scale but also has orchestral accompaniment. Put simply he had access to plenty of resources and wasn't shy about using them. His music which can be very charming is characterised by lyrical melodies, elaborate instrumental figurations, contrasted tempi and dynamics. As well as his liturgical and religious music he composed musical comedias and zarzuelas and was listed by the Diario de México as being an 'outstanding composer'. There was plainly a lot of cross-over in his music. You'll hear all the features I listed above in this setting of Quem terra pontus sidera [aethera] in fact it's downright operatic. Enjoy :-).
