By Ralph Paulsen-Bahnsen. “Gloria in Excelsis Deo”, for 2 mandolins, contains 24 Christmas songs. Next to an assortment of primarily German arrangements, the booklet also contains a few popular international Christmas songs the likes of “Jingle Bells” or “O How Joyfully”. Joining in, next to an easily playable first mandolin, is a more advanced second mandolin. This enables performers at differing skill-levels to perform together harmoniously. Furthermore, the compositions are not exclusive to the mandolin, they are also suitable to performed on the violin, guitar or the zither.
