Periodicity: Interpreting Waves of Information in Osundare’s Harvestcall

Main Article Content

Taofeek Olaiwola Dalamu


The study investigated the waves of information of Osundara’s Harvestcall to show textual movements as layered by the poet. To achieve that objective, the poem of about 76 lines was collapsed into 44 clauses as a tradition that paves a way for systemic analysis of texts in different shapes, sizes and constructs. Halliday’s Theme and Rheme served as analytical tools that processed the text after which the investigation utilized tables and graphs as indicators of waves of information of Harvestcall. The analysis reveals three separate waves of the text, namely: (i) sectional organization – perceives Sections I, II and III are the Theme while Section IV is the Rheme; (ii) clause constructs – demonstrates multiple Themes that flow to rhematic structures; and (iii) time frame exposition – espouses the past farming commitment as Theme and its current neglect as Rheme. In addition, observation shows waves interference. That is, the switching of Theme 2 and Subject Theme in Sections I, II and III for Subject Theme and Theme 2 respectively in Section IV. As linguistic concepts can reveal so much meanings of a literary device, the study suggests their applications across the board of genres of literature.
