Introduction
In the previous lessons we established what a raag is in broad terms — a melodic framework that evokes a specific emotional state — and we surveyed the thirty-one raags that structure Sri Guru Granth Sahib Ji. But understanding raag at a deeper level requires entering its internal grammar: the ascending scale (ਆਰੋਹ, aroha), the descending scale (ਅਵਰੋਹ, avaroha), the dominant note (ਵਾਦੀ, vadi), and the sub-dominant note (ਸੰਵਾਦੀ, samvadi). These four elements, taken together, are what give each raag its unique personality. Without them, a collection of notes is merely a scale; with them, it becomes a living musical being.
This lesson moves from the structural overview of the raag system into its technical grammar. We will examine how the aroha and avaroha differ from a simple scale, how the vadi and samvadi notes function as the emotional anchors of a raag, and why these concepts are essential for any serious student of Gurmat Sangeet (ਗੁਰਮਤਿ ਸੰਗੀਤ). We will also look at how classical Indian musicology — particularly the Natya Shastra tradition and its later developments — shaped the theoretical framework that the Gurus inherited and then transformed through the lens of Gurbani.
By the end of this lesson, you will be able to read a raag description in a musical treatise and identify its structural elements, and you will understand why the same seven notes arranged in slightly different ways produce radically different emotional textures.
Aroha and Avaroha: More Than Going Up and Down
The most common misunderstanding about aroha and avaroha is that they are simply a scale played forwards and backwards. In reality, a raag's ascending and descending movements are often asymmetrical. A singer may skip certain notes on the way up (ਵਕ੍ਰ, vakra, meaning crooked or zigzag movement) and include them only on the way down, or the phrase may leap across intervals in ways that feel counterintuitive to a listener trained only in Western scales. This asymmetry is not an error — it is the defining character of the raag.
Take Raag Bilawal, one of the ten parent raags (ਠਾਟ, that) in the Bhatkhande system. Its aroha uses all seven natural notes (ਸ਼ੁੱਧ ਸੁਰ, shuddh sur) without exception, which gives it a quality of brightness and evenness. But this evenness is deceptive: the specific phrases (ਪਕੜ, pakar) that characterize Bilawal — the melodic fingerprints a trained listener recognizes — involve particular inflections on the Gandhar (third note) and Dhaivat (sixth note) that distinguish it from other all-natural raags. The aroha and avaroha establish the boundary; the pakar fills in the personality.
In SGGS, the raag headings appear at the beginning of each new section and are followed by the name of the Guru who composed those shabads, the number of hymns (ਅਸ਼ਟਪਦੀ, ashtpadi, ਚਉਪਦੇ, chaupade, etc.), and sometimes the rhythmic cycle (ਤਾਲ, taal) to be used. The scribes and singers who first performed these shabads were trained musicians who understood that the heading Raag Aasaa (ਰਾਗੁ ਆਸਾ) was not merely a label but a complete performance instruction — including its aroha, avaroha, and characteristic phrases.
For the student of Gurmat Sangeet, learning to sing or play the aroha and avaroha of each of the thirty-one raags is the beginning of musical literacy, not an end in itself. The goal is to internalize the raag's shape so deeply that the notes arise naturally, without calculation, in the same way a poet writes in a meter without consciously counting syllables.
Vadi and Samvadi: The Two Pillars of Emotional Identity
Every raag has one note that functions as its principal emotional center, the note on which the singer naturally rests and around which the melodic movement revolves. This is the vadi (ਵਾਦੀ), sometimes translated as the king note or the speaking note. The samvadi (ਸੰਵਾਦੀ) is the second most important note, often a fourth or fifth away from the vadi, and it functions as the vadi's resonant partner — its echo, its complement, the note that answers when the vadi speaks.
The relationship between vadi and samvadi is sometimes described in classical texts as a conversation between two voices. This is not merely poetic: in performance, a skilled ragi (ਰਾਗੀ) will return to the vadi repeatedly throughout a shabad, and the samvadi will appear at structurally significant moments — at the end of a phrase, at the turn of a verse, at the moment of greatest emotional intensity. Listeners who are trained in classical music often feel a sense of resolution or rightness when the vadi is touched, even if they cannot name the note.
In the context of SGGS, this has profound implications. When Guru Nanak Dev Ji composed a shabad in Raag Siri (ਰਾਗੁ ਸਿਰੀਰਾਗੁ), the vadi of that raag is not incidental — it is the note that the Guru's words were designed to rest upon. The theology of the shabad and the emotional grammar of the raag reinforce each other at precisely these points of rest. This is what scholars of Gurmat Sangeet mean when they say the raags were chosen, not assigned arbitrarily.
Understanding vadi and samvadi also helps explain why the same shabad sung in the wrong raag feels wrong even to untrained listeners. The emotional resting points shift. The sense of resolution comes in the wrong places. The conversation between the two pillar notes becomes incoherent, and with it, the emotional logic of the composition unravels. This is one of the strongest arguments in the scholarly debate about raag-based versus popular-tune kirtan.
Pakad and Chalan: The Melodic Fingerprints of a Raag
Beyond aroha, avaroha, vadi, and samvadi, every raag has two additional defining features: the pakad (ਪਕੜ) and the chalan (ਚਲਣ). The pakad is a short characteristic phrase — typically four to eight notes — that identifies the raag immediately to a trained ear. It is the melodic fingerprint. The chalan is the overall movement pattern of the raag: how it tends to unfold over the course of a performance, which registers it favors, where it lingers, and where it moves quickly.
In classical Hindustani practice, a student learning a new raag is first taught its pakad. This short phrase encapsulates the raag's essential character more efficiently than any theoretical description. Once the pakad is internalized, the student can begin to explore the full chalan — the characteristic ways the raag moves through its entire range — and eventually compose or improvise within the raag's boundaries.
For students of SGGS, the pakad and chalan are the reason why two raags with very similar aroha and avaroha can feel completely different. Raag Bhairavi and Raag Asavari, for instance, share many of the same notes, but their pakads diverge sharply, and their chalans move through the register in distinct ways that produce entirely different emotional worlds — Bhairavi evoking pathos and devotional longing, Asavari carrying a quality of dignified gravity. Both appear in SGGS, and both carry shabads whose theological content aligns with their distinct emotional characters.
A practical exercise for any student serious about Gurmat Sangeet is to listen to a skilled ragi perform a shabad and attempt to identify the pakad — the repeated short phrase that returns like a refrain in the melodic movement. With practice, these fingerprints become recognizable across different shabads, different Gurus, and different centuries of composition, revealing the raag as a stable emotional entity that transcends any individual text.
Key Terms
- ਆਰੋਹ (Aroha) — The ascending movement of notes in a raag, often asymmetrical and not simply a rising scale.
- ਅਵਰੋਹ (Avaroha) — The descending movement of notes in a raag, which may include notes skipped in the ascent.
- ਵਾਦੀ (Vadi) — The principal or king note of a raag; the emotional center around which the melody revolves.
- ਸੰਵਾਦੀ (Samvadi) — The second most important note of a raag, often a fourth or fifth from the vadi, functioning as its resonant partner.
- ਪਕੜ (Pakad) — A short characteristic melodic phrase that identifies a raag to a trained listener; its melodic fingerprint.
- ਚਲਣ (Chalan) — The overall movement pattern and characteristic unfolding of a raag across its full range.
Discussion Questions
- Why might asymmetry in the aroha and avaroha be considered a feature rather than a flaw? What does this tell us about how Indian classical music understands melody differently from Western scales?
- The vadi note is described as the emotional center of a raag. Can you think of a parallel concept in another art form — poetry, visual art, architecture — where a single element anchors the emotional identity of the whole work?
- If the pakad is the melodic fingerprint of a raag, what are the implications for a ragi who performs a shabad in a raag without knowing its pakad? Is the shabad still being sung in that raag, or has something essential been lost?
- Scholars debate whether strict raag fidelity is achievable or even desirable in congregational kirtan settings. Where do you stand, and what evidence from this lesson supports your position?

Key Takeaways
- Aroha and avaroha are not simply scales played forward and backward — their asymmetry is central to a raag's identity.
- The vadi and samvadi notes function as emotional anchors, and their placement within a shabad's melodic movement carries theological meaning.
- The pakad is a short melodic fingerprint that allows trained listeners to identify a raag immediately, independent of any specific text.
- Understanding these technical elements deepens appreciation of why the Gurus assigned specific raags to specific bani — the musical grammar and the spiritual message reinforce each other precisely.
Homework
Select any one of the thirty-one raags in SGGS and look up its aroha, avaroha, vadi, and samvadi in a reliable source (a music encyclopedia, a Gurmat Sangeet textbook, or a vetted online resource). Then listen to a kirtan recording of a shabad in that raag for at least fifteen minutes. In 350–450 words, describe how you can hear the vadi note functioning as an emotional anchor in the performance, and whether the ascending and descending movements feel symmetrical or asymmetrical to you. You do not need to name specific notes — write from careful, attentive listening.
