The piece takes between forty minutes and one hour to perform, although the score specifies that it should have a duration of 45 minutes. It is scored for a solo
violin and eight
magnetic tapes. A performance also requires eight to ten
music stands, located in many different places on stage as well as amongst the audience seating area. Nono specified that
La lontananza is not "in any circumstance a concerto for solo and accompaniment", Tapes 3 and 4, however, have a definite structure, with five elaborations of one initial fragment lasting for about twelve seconds. This fragment consists of a slow melody on the IV string, played
with the wood of the bow, with accents and sforzato intersparsed, joining dialogues and sounds such as exclamations, coughing and laughs, as well as ambient noises, such as the studio door opening and closing. This "assembled pseudo-working session" is specifically designed to resemble a live recording studio, upon which Nono later made repetitions with modifications. Tracks 5 and 6 feature other miscellaneous sounds prominently, i. e., sounds that do not come from the violin. Here, Nono mixes voices, conversations, coughs, laughs, and other electric sounds, such as metallic resonances, buzzes, bangs on doors, etc. The two tapes are constructed using a recognizable pattern that is 20 seconds long. Spatialization is present in these two tracks, as Nono was very concerned with the spatial movements within the tapes. Tapes 7 and 8, finally, follow the same formal structure as tapes 3 and 4. The tapes consist of an initial fragment that is around 12 seconds long and five reinterpretations and elaboration on the same original material. This initial material, however, can only be inferred, as each one of the repetitions rearrange the order of elements, the layers, and the dynamic settings of each element. After the first presentation of the fragment, the listener hears a gradual process of deformation which renders the end result hard to decipher. == Recordings ==
