et tenebrae factae sunt in terra (and darkness covered the earth) is a reflection on the crucifixion. This connection is seen primarily through the use of four quotations. The first is a statement of the first 4 notes (F#, G, E#, F#) of Bach’s second "Kyrie" from the B Minor Mass. This is first presented in the first bar of the cello and this figuration permeates throughout the work. The second and third quotations are a four-part chant and Gregorian chant from Victoria’s Reproaches for Good Friday. Finally, the hymn tune Picardy (Let all mortal flesh keep silent) is heard in combination with the above.
