Saraswati

Closest Western scale / mode

Lydian dominant subset · asymmetric

With Sa = C: ascent C D F♯ G A; descent C B♭ A G F♯ D C. The third is absent; a janya of Vachaspati, not a melakarta.

A pitch-set comparison, not an exact raga equivalence. Carnatic gamakas and characteristic phrases are not captured by a Western scale; acoustic piano cannot reproduce continuous pitch ornamentation.
