Omnipresence of Rhythm) is a 2019 Indian Tamil-language musical drama film written and directed by Rajiv Menon.

The film stars G. V. Prakash Kumar and Aparna Balamurali, with a supporting cast including Nedumudi Venu, Vineeth, Kumaravel, Santha Dhananjayan, and Dhivyadharshini.

Returning to direction after 19 years, Menon makes a comeback with a film that is relevant, entertaining, and inspirational in parts.

Peter becomes good friends with Nandagopal 'Nandu', a NRI and a Harvard University PhD drop-out who came to learn mridangam from Iyer.

Meanwhile, Mani joins as a judge in a classical music instrument reality show called 'Sangeetha Samrat' with the help of his younger sister Anjana who is a crooked socialite and works as a VJ.

Then with no option left, Peter gets ready to play mridangam which gets severely humiliated by Mani and Anjana, making him seem useless and directly criticise Iyer.

[5] Pre-production work took place in mid-2016, and the team finalised Sai Pallavi to play the female lead role.

[6] Other actors including Nedumudi Venu and Cheenu Mohan were also approached to play key roles in the film, but production failed to take off in November 2016 as planned and the project was delayed.

[7][8] In March 2017, Menon denied that the film was dropped and noted that a promotional photo shoot with Prakash Kumar was imminent.

[9] Prakash Kumar revealed that the story was set in two states and was inspired by incidents from the lives of real musicians.

[10] During the period, Prakash Kumar also took professional mridangam lessons from percussionist Umayalpuram Sivaraman to equip himself for the character.

Sai Pallavi's unavailability meant that the team replaced her with Aparna Balamurali, after Menon was impressed with her performance in the Malayalam film, Maheshinte Prathikaaram (2016), and called her for a successful audition.

[12] An ensemble cast of Nedumudi Venu, Santha Dhananjayan, Vineeth, Kumaravel, Sumesh and Athira was also announced with the launch, while Ravi Yadav and Anthony were confirmed as the film's cinematographer and editor respectively.
