Haricharan sang for both the characters 'Krishna' and 'Arjuna' by bringing alterations in his voice. As per the producer, S. Sashikanth, "Every song in this movie has a concept behind it. With "Yaarumilla" – that particular idea was based on the romance between Kitappa and KB Sundarambal. There were letters that Sundarambal had sent to Kitappa which are supposed to be on par with Shakespearan love letters! So the song's inspiration comes from that." In an interview with Deccan Chronicle Rahman was quoted saying, "Being a period film and the subject being about a dramatic trouple, I needed to go into the subject in some depth. Apparently, it was done for people to relate with the music of that era with immediate ease." The film has 20 bit songs of varying lengths that partly form the score. At The Economic Times, Rahman noted, "The limitation was the throw (performing on stage needs high-pitched tunes with dynamism) at which the songs needed to be composed." In October 2013, singer Madhushree announced that she had performed a duet titled "Thamana" with S. P. Balasubrahmanyam, however the track eventually did not feature in the soundtrack album. Seven original songs in each of the plays are featured in the film. All the compositions reflect the sound and musical preferences of the 1920s era. Director Vasanthabalan selected old verses of Madurakavi Bhaskaradas so as to tune them for selected songs. All the songs were recorded by early May 2014. Vasanthabalan confirmed in early September 2014 that Rahman was working on the background score of the film in his studio in Los Angeles.
