Arohana, Arohanam or Arohan, in the context of North Indian Classical Music and South Indian Classical Music, is the ascending scale of notes in a raga[1]. The pitch increases as we go up from Shadjam (Sa) to the Upper Stayi Shadjam (Sa).
In Multani, the aroha is 'N S g M P N S' (lowercase notes are the lower forms, while uppercase notes are the higher forms, and an apostrophe preceding or following a note denotes the lower or higher octave – see swara).
In Sankarabharanam ragam (29th Melakarta in 72 parent ragam scheme of Carnatic music) the Arohana is S R2 G3 M1 P D2 N3 S[1]. See swaras in Carnatic music for explanation of notation.
In Abhogi raga, which is a janya ragam of 22nd melakarta Kharaharapriya, the Arohana is S R2 G1 M1 D2 S[1]. In this ragam certain notes are excluded so the raga is totally changed.
