"Create a Bengali devotional song titled 'Durga Maa, Agomoni' in D-flat major, suitable for celebrating the Durga Puja festival. The song should have a soothing and uplifting mood, with a medium tempo of around 80-90 BPM. It should start with a gentle instrumental introduction that captures the essence of a cool autumn breeze and the fragrance of Shiuli flowers. The verses should feature a traditional Bengali arrangement, incorporating Indian classical instruments like the tabla, sitar, and flute, with a touch of modern elements such as a soft acoustic guitar and light percussion. The chorus should have a dynamic, uplifting feel that emphasizes the celebration of Durga Maa's arrival, with a powerful combination of vocals, harmonium, and dhol. The bridge should have a calming, spiritual quality, featuring the flute and sitar to convey a sense of peace and devotion. The outro should conclude with a gradual fade-out of instruments, highlighting the vocals with a sense of reverence and devotion. The overall composition should evoke a sense of joy, celebration, and divine energy, resonating with the spiritual and cultural essence of Durga Puja."
