Abheri is a raga (musical scale) in Carnatic music (South Indian classical music). It is a Janya raga (derived scale), whose Melakarta raga (parent, also known as janaka) is Kharaharapriya, 22nd in the 72 Melakarta raga system.
Its ārohaṇa-avarohaṇa structure (ascending and descending scale) is as follows (see swaras in Carnatic music for details on below notation and terms):
ārohaṇa : S G2 M1 P N2 S
avarohaṇa : S N2 D2 P M1 G2 R2 S
(Chathusruthi Rishabham, Sadharana Gandharam, Suddha Madhyamam, Chathusruthi Dhaivatham, Kaisiki Nishadham)
In addition to these swaras, there are gamakas which also form part of Abheri, like any other raga in Carnatic music.
The ascending scale is same as that of Udayaravichandrika raga (also known as Shuddha Dhanyasi), while the descending scale is that of Kharaharapriya raga.
There are some differing views on swaras in the scale of Abheri. It is considered a Bhashanga raga (scale has an anya swara, that is, a note which is not in the parent melakarta raga, in this case Kharaharapriya raga), with introduction of Suddha Dhiavatham (D1) in some phrases of the raga. A different view is that this raga is a janya of Natabhairavi (which has D1, suddha dhaivatham, in place of D2), with D2 being the anya swara (external note).
Bhimpalasi (or Bheemplas) of Hindustani music sounds pretty close to Abheri.
