Purnima Sen's music is meticulously crafted, having an esthetic coherence and maturity, with all the elements - poetic, melodic, and rhythmic - in balance. Its vintage quality has a freshness and allure, as Purnima presents Agra vocalism, shorn of its ruggedness. "Khem Kalyan" is a rare and "precious" Kalyan variant. "Megh Malhar" is a mature raga associated with the rainy season. "Khamaj" is romantic and playful, one of the pillars of the thumri genre.
