तुमको मेरी क़सम

The title track of Tumko Meri Kasam is the film's emotional capstone — a three-voice composition where Neeti Mohan, Papon and Prateek Walia each carry a section of a life-long vow. The song's biographical weight is considerable: it is effectively the sound of a marriage that survived the birth of an entirely new field of Indian medicine. Papon's voice, with its Assamese folk undercurrent, brings an unexpected regional dimension to the track.

Builds from a solo piano intro to a full orchestral climax. The three-voice arrangement is Prateek Walia's most ambitious production choice in the album.

The title phrase 'tumko meri kasam' is both a vow and a plea — swearing by the relationship itself. An unusual grammatical construction that gives the lyric its power.

Used over the film's closing montage — the IVF clinic's growth, the couples helped, the families created — and Ajay and Indira watching it all.

Title tracks of biopics often become anthems for the communities they represent — Tumko Meri Kasam has the potential to resonate with India's IVF community.
