Aroha and Avaroha: The Ascending and Descending Lines of a Raga
Every raga has a characteristic way of climbing toward the octave and a characteristic way of coming back down. Hindustani theory names these two shapes the aroha (ascent) and avaroha (descent), and together they're one of the first things written down about any raga — before vadi and samvadi, before anything else. The single most important thing to know going in: aroha and avaroha are very often not mirror images of each other. That's not a simplification or an error in a transcription — it's normal, and it's part of what gives a raga its identity.
A straightforward example: Yaman
Yaman is a good first raga to look at because its aroha and avaroha are both close to a straight scalar run — no zigzagging, just a full seven-note ladder each way. This site's own Ragas reference has it as:
- Aroha: N, R G m P D N S' — an approach from the Ni just below Sa,
then a straight climb through Re, Ga, tivra
Ma (written
Ma#in prose,min Compose notation), Pa, Dha, Ni, up to Sa. - Avaroha: S' N D P m G R S — the same seven notes, descending in the same order.
Yaman's aroha and avaroha happen to line up almost exactly, which makes it a clean baseline before looking at a raga where they don't.
A five-note example: Bhupali
Bhupali drops two notes — Ma and Ni — entirely, using only five:
- Aroha: S R G P D S'
- Avaroha: S' D P G R S
Same five notes both directions here too, just in reverse order. Between Yaman and Bhupali you've already seen the two most common shapes: a straight run up, matched by the same straight run back down.
When they genuinely differ
Not every raga is this tidy. Hindustani theory has names for how many notes a raga's aroha or avaroha actually uses:
- Sampurna — all seven notes (Yaman is sampurna both ways).
- Shadava — six notes, one dropped.
- Audava — five notes, two dropped (Bhupali is audava both ways).
A raga can even mix these — sampurna on the way up, shadava on the way down, or the reverse — and a raga's note count doesn't have to match between its two directions at all. On top of that, a line can be vakra (crooked): instead of climbing or falling in a straight ladder, it zigzags, touching a note, stepping back, then continuing. This site's own Alhaiya Bilawal is a clear example — its aroha skips Ma on the way up entirely, only bringing it into the avaroha, and its avaroha itself zigzags in a way a straight scale run never would. None of this is a corrupted or "wrong" version of a straight scale — it's exactly the kind of melodic detail that the thaat system alone can't tell you, since thaat only fixes which seven notes are available, not the specific path a raga actually takes through them.
Where to find this for any raga on the site
Every entry on Ragas lists its aroha and avaroha directly, alongside its vadi and samvadi and its thaat system. Reading the aroha and avaroha side by side, rather than assuming one mirrors the other, is the first real analytical habit worth building when you pick up a new raga.
Try it yourself
Practice this: open Compose, pick a raga from Ragas, and type out its aroha in one row and its avaroha in the next. Hit play on each and listen for whether the climb and the descent actually feel like the same path in reverse — with Yaman they will; with something like Alhaiya Bilawal, you'll hear the asymmetry directly instead of just reading about it.
