Ranjith under his socio-cultural activity Neelam Panpattu Maiyam.

[4] Tenma got this opportunity to compose the music for the film, due to the overwhelming response for the band's debut album "Magizhchi" which was released in December 2018, at the Vaanam Arts Festival, which was initiated by Ranjith himself.

The lyrics were written by Umadevi and the song was rendered by K. Chitrasenan, Arivu, Gana Muthu and Ezhumalai, who were a part of The Casteless Collective band.

The second single track titled "Maavuliyo Maavuli" written by Thanikodi and sung by Tenma and Shweta Mohan was released on 4 November 2019.

The tracklist was revealed on 21 November 2019, with Umadevi, Thanikodi, Muthuvel and Arivu penning the lyrics of the songs.

For "Nedu Vazhi" she stated "Vignesh Ishwar’s voice depicts a beautiful portrait of a son’s relationship with his father.

Shakthisree Gopalan and Chinnaponnu conjure a world of peace, yearning to let go off violence and war.

She further added "Irul Vaanam" as "a romantic soliloquy that is pleasantly rendered by Subiksha Rangarajan" She added "Chinna Machan (from Charlie Chaplin 2) fame folk singer Senthil Ganesh injects his characteristic energy into Iruchi, which makes brilliant use of harmonium and Nadaswaram."

She finally concluded that "It is clear from Tenma’s rich soundscape that it is designed to organically flow with the film’s narrative rather than stick out as individual pieces.
