This is the first time that the film festival has a signature tune.
`The 17th Jio MAMI Mumbai Film Festival is about creating, celebrating and nurturing cinema. I am very pleased to support the festival. I hope the people of Mumbai and India come and partake in this incredible movie feast,` Rahman said in a statement.
Anupama Chopra, festival director, 17th Jio MAMI Mumbai Film Festival, said it's an honour having Rahman onboard.
`Movies and music are inseparable in India. We are grateful for his generosity and support. We are also grateful to all the work put in by Vikramaditya Motwane and his team, and all the talent that made time for Jio MAMI,` she added. Rahman's creation is used for the promo film that will be played during the festival, which will be held from October 29 to November 5.
Currently, it is featured as part of the branding at the opening and closing of the festival campaign film.
However, the tune will be played in full at the opening ceremony later this month.
The festival's campaign film, directed by Motwane, features A-list names such as Shyam Benegal, Amitabh Bachchan, Aamir Khan, Farhan Akhtar, Kangana Ranaut, Nimrat Kaur and the Jio MAMI Mumbai Film Festival chairman Kiran Rao.
In the film, the celebrities narrate their personal stories for their special relationship with Mumbai, the city of dreams, and with their collective passion - cinema.
