To analyze the arousal state, ‘Plutchik's' emotion model has been employed and to find the valence, a Fuzzy-based model has been engaged. Emotions are analyzed based on the Arousal-Valence Model. This article analyzes the changes in Tagore's emotion in Song-Offerings with the passage of time (1895-1912). Earlier, most of the research work on Song-Offerings was based on Zipf's law or bibliometric laws. In the proposed work ‘Song- Offerings': A collection of poems and songs composed by Rabindranath Tagore, for which, Tagore received the Nobel Prize for literature in 1913, has been analyzed. The works of a poet give philosophical insights about the beauty and mystery of nature, socio-economic conditions of that era, besides his personal state of mind. The emotion of poets is reflected through poetry/songs. The emotions of humans can be observed through tears, smiles, etc.
