We published some Christmas Carols from the I.C.A. library in 2009.
And this year, I’ve added some tunes from an 18th century manuscript from Antwerp, transcribed for Treble and Baritone. They should fit the Christmas mood very well, provided you do play them at a solemn pace. In absence of a treble concertina, pick any other melody instrument for the 1st voice. The tunes also sound well just playing the 1st voice alone.
