Praetorius made it his life's work to make the Italian Baroque style accessible to even the humblest village choir. The choir (always boys or men it wasn't until Mozart's time that female sopranos performed German religious music) was sometimes augmented by violins, viols, or wind instruments. I find Pueri nostri concinite 'Singet und klinget' like much of his Christmas music to be well-nigh irresistible it's lively, warm, and cheerful and well within the range of the most meagre village choir. It's it's from the Puericinium and set for four equal voices. Praetorius written in the concertanto manner and the boys solos are augmented by tutti choruses in which the congregation could join with a will. It's nowhere near as well known as 'Quem Pastores Laudavere' about which I wrote two years ago (see: Prætorius: Quem Pastores Laudavere – Westminster Cathedral Choir) which is a shame because it deserves to be known and sung far more. Enjoy :-).
