Tone is an inclusive term with manifold definitions. Each researcher, therefore, interprets it differently depending on how he/she approaches it in the text. In fact, tone is the echo of the writer or poet’s voice communicating with those who are willing to hear such mesmerizing songs. As a principal element, tone is divided into many minor (local) tones. In this research, colloquial tone has been examined in various stylistic tendencies and genres of present-day Mazandaran poetry. To this purpose, researchers have introduced, classified, and analyzed the processing techniques of tone in the poetry of forty Persian poets from 1972-2021. Findings indicate that in order to achieve colloquial tone, Mazandarani poets have benefitted from five main techniques (framework, sound, music, language, and rhetoric) and 25 minor techniques in their poetry. Given the research data, the musical features and four minor techniques have had significant frequencies. Moreover, regarding linguistic techniques, local-ethnic and humorous tones are found to be significantly frequent. Research methodology used in this study is mixed method (qualitative and quantitative) which makes use of reference documents and reliable Internet sites.
