A treat for the Christmas season --- the Osiander setting of "Christum wir sollen loben schon" put to the Latin hymn-text for the liturgical use in the E.F. of the Roman Rite. This is effective with organ, unaccompanied, as well as alternatim with the chant (whether the melodic variant printed in the current books or the one on which this chorale tune was based).

Hope you get some use out of it!
