The baramasi songs of chittagong and pabna are called Sita's Baramasi and Nila's Baramasi. The stories of the two songs are similar in many ways. In the following lines from Sita's Baramasi, sita laments her separation from ramachandra during the month of Asadh. She describes the heavy rains during this month and longs to be reunited with her husband: 'Asadh masete dekha ghana barasan/kotha prabhu Ramachandra and devar Laksman/Karmaphale Dashanane aniyachhe hari/ Dharmik Laksman more nao na hari' (Look at the heavy rainfall of the month of Asadh./where is Lord Ramachandra and my brother-in-law, LaksmanFoodgrain/The ten-headed' [Ravana] stole me away because of my misdeeds./Devout Laksman take me back.)
Kalketu Upakhyan by the 16th-century poet mukundadas contains Phullarar Baramasi, which describes the sufferings that Phullara endured for twelve months. [Abdul Wahab]
