In Dulci Jubilo by Samuel Scheidt - for double choir plus two obbligato parts
This wonderful setting of In Dulci Jubilo was published in 1620 in “Cantiones sacrae“. I transposed it down a step to make it easier to sing, since I’m not really a singer. ;)
The recorders I’m playing are as follows: Ganassi soprano in C by Jean-Luc Boudreau; Tenor in C, Basset in G, and Bass in C by Francesco LiVirghi; and Contrabass in F by Friedrich von Huene.
A scan of the original “Cantiones Sacrae“ can be found on IMSLP, as well as modern editions of this and many other pieces in it.
