Kafi

Kafi names its own thaat and is close to the simplest possible statement of it: komal Ga and komal Ni over an otherwise shuddha scale, sampurna in both directions with no notes omitted. That makes it the natural point of comparison for the other Kafi-thaat ragas covered here — Bageshri and Bhimpalasi both borrow Kafi's komal Ga and komal Ni but restrict which notes appear in the ascent, where Kafi itself uses all seven freely. Most sources give Pa as vadi with Re as samvadi, though a few give Sa instead of Re; both are valid fourth-or-fifth relationships to Pa under classical interval rules, so the disagreement is more about tradition than a right-or-wrong answer. Traditionally placed in the second quarter of the night, Kafi's plaintive, folk-adjacent quality made it a historic home for Holi and spring songs, and it remains one of the most common bases for thumri, dadra, and hori outside the khayal tradition.
