Mohanakalyani

Closest Western scale / mode

Major pentatonic ascent / Lydian descent

With Sa = C: ascent C D E G A; descent C B A G F♯ E D C. Its two directions have distinct pitch sets.

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.
