This collection of eighteen choral arrangements of melodies from the Protestant hymn book is meant to be used in services and little concerts. Rather varied with regard to the compositional approach of the individual arrangements, the collection, like a kind of informative selection, shows the different possibilities of how to deal with a tonal melody in post-modern pluralism. The stylistic patterns presented can easily be drawn out and transferred to other chorales for the purpose of an improvisation exercise, which serves as the educational aspect of this organ book.
