Structuralist narratology does not provide methods and models to examine silence, ellipsis, and gaps in the text. This paper tried to examine the aspects of silence, ellipsis, and gaps in the narrative, by employing a text-based and analytical method. The text Nocturnal Harmony of Wood Orchestra was chosen for the analysis which is unreliably narrated. In order to identify unreliable narrator and also text’s unreliability, silences and narrative ellipsis were studied. Narrative style and related elements such as focalization, distance, narratee and the narrator’s motivation along with structural elements influence the types of ellipses in the narrative or they are influenced by the gaps of the unreliable narrative. The form can be used as a decentralization device to cover the silence or to create suspension by creating a gap. Moreover, anachronism can create or conceal the gaps and silence in narrative and frequent occurrences is a way of presenting and also covering the narrative gaps. Studying the relation between events and the catalyzer is also another way to understand the dimensions of silence and the devices that cover ellipses in the narrative. All of these were employed to study silence and ellipsis in the text.
