Written in the 1970s, Dieter Schnebel's arrangements of the Contrapuncti I, VI and XI from Johann Sebastian Bach's The Art of Fugue have long since been considered classics of contemporary choral music and of the cultivation of Bach's music. The works, which have previously been available in manuscript editions only, are now published as new editions in a high-quality, easily legible notation in a convenient standard format which adequately displays the works' polyphony.
