The arrangements in this collection represent 80 percent of Duruflé's entire a cappella oeuvre, with three from the four Quatre Motets sur des thèmes grégoriens Op. 10 (1960) alongside Notre Père Op. 14 (1977/1978). The name SAM-Klang takes the three voice parts from the arrangements -- Soprano, Alto and Men -- and combines it with the Scandinavian and German words for sound to create the portmanteau word sound together or harmony. The series offers basic and advanced choral repertoire. In addition to new repertoire and new arrangements, you will also find essential parts of the classical German, Scandinavian, French and English SATB repertoire, carefully and considerately reworked for SAM. The arrangements retain the characteristic features of the original movements and have almost the same richness of timbre, resulting in works which sound nearly unchanged to an audience. Piano reductions of all choral movements facilitate rehearsal preparation. The arrangements offer development opportunities for all voice sections, bringing new life and new quality to SAM choir work. SAM-Klang enables youth choirs to gain access to classical choral literature and ensures that mixed choirs who face challenges in finding singers for all male voice parts continue to have access to well-loved repertoire.
