This collection of short pieces for strings was conceived for both advanced teaching purposes and equally for use in concerts with uncommon combinations of instruments.

The collection carries the opus no. 27. The Roman numerals after the opus no. refer to the number of players (I = Solo, II = Duo, III = Trio, etc.), the capital letters to the same or different instruments (A = the same instruments, B = one other different instrument, C = two other different instruments, etc.), the Arabic numerals to the number of the particular piece.

The title of the work is taken from the poem "Finsternis" [Darkness] by Paul Celan, written in 1941. The poem speaks of painful loss in times of violence, and culminates in the line that was chosen as the title of this piece. This line of poetry is ambiguous. A scream implies the reaction to an act of violence, and evokes associations such as the cry of pain, the cry of horror, the cry of death. The shadow, in turn, has something to do with the past and with transience. So, if the poet says "my shadow" and "your cry," it means that there must have been a person close to the author that was apparently abused. Whether this person still exists or not, however, is not mentioned. The "struggle," on the other hand, suggests that the emotional overcoming of this event is still ongoing. So we have a very personal and painful, probably often recurrent, memory of a traumatic experience. The "and" was deliberately added to the title to further emphasize the ambiguity of the line: an ambiguity that leaves room for a wordless music of painful sensation.
