Introduction
In our last lesson, we established the crucial distinction between a thaat (a static, theoretical scale) and a raga (a living, breathing melodic personality). We touched upon the idea that a raga's unique character comes from a set of grammatical rules. Today, we will unpack the most fundamental of these rules.
This lesson focuses on three essential components that form the very skeleton of any raga: the aaroh (ascent), avroh (descent), and pakad (signature phrase). By understanding these, you will move from knowing that a raga has a personality to knowing how that personality is structurally defined. Think of it as moving from understanding the concept of an object in programming to examining the specific methods and properties that define its structure and behavior.
Aaroh and Avroh: The Melodic Pathways
At the most basic level, the aaroh defines the sequence of notes used when ascending in pitch, and the avroh defines the sequence for descending. The terms themselves come from Sanskrit: aarohan (आरोहण) means to climb or ascend, and avrohan (अवरोहण) means to descend.
For a quick, clear definition, let's start with a video from the VoxGuru channel.
Introduction to Hindustani Music | VoxGuru ft. Shivani Mirajkar
This short clip introduces the core concepts of Aaroha and Avaroha in English.
Watch the opening section from the beginning, where the instructor, Shivani Mirajkar, defines the ascending (aroha) and descending (avaroha) patterns as the first things one learns in a raga.
This simple definition, however, can be misleading. A raga's aaroh and avroh are rarely as straightforward as climbing up and down a ladder. This is a key difference between a raga and a simple scale. A raga's path can be indirect, twisted, or vakra (वक्र), meaning "crooked" or "zigzag."
The following video, in Hindi, provides a more nuanced explanation of this concept.
Aroh - Avaroh||Pakad||Nyas ke swar|| रागों का आरोह-अवरोह, पकड़, न्यास के स्वर || राग के लक्षण ||
The presenter in this "Soft Music Theory" video explains the concepts of Aaroh and Avroh in detail, including the important idea of vakra movement.
Please watch the following segments: First, the definition where he explains the literal meaning of aaroh as "climbing order." Next, the definition of Avroh as the "descending order." Most importantly, pay close attention to the section from this point on vakra. The presenter explains that in some ragas, the movement is not linear. He uses Raga Kedar as an example to show how the notes move in a zigzag pattern, yet the overall direction is still ascending. Finally, he offers a more refined definition, which is crucial for our understanding. He states that the aaroh and avroh are the ascending and descending movements of the notes according to the raga's chalan (characteristic flow).
This refinement is key. The aaroh and avroh are not just a list of notes; they are a prescribed melodic law. They dictate the mandatory path a musician must take through the notes of the raga.
Let's illustrate with two examples:
1. A Simple (Saral) Raga: Bhupali
Raga Bhupali is a pentatonic (Audav) raga. It omits Ma and Ni. Its pathways are straightforward.
- Aaroh:
- Avroh:
Here, the path is linear, moving directly from one note to the next in the sequence.
2. A Crooked (Vakra) Raga: Kedar
Raga Kedar, as mentioned in the video, also uses a limited set of notes but its path is much more complex.
- Aaroh: or sometimes .
- Avroh:
Notice how the melody doesn't move in a straight line. In the aaroh, it touches Ma, goes to Pa, then jumps to Dha and Ni. In the avroh, it meanders around Pa and Ma before finally descending. This vakra gati (crooked movement) is essential to the identity and beauty of Raga Kedar. Playing the notes in a straight line would destroy its character.
Pakad: The Raga's Signature Phrase
If the aaroh and avroh are the prescribed highways of a raga, the pakad (पकड़), which literally means "to catch," is its unique landmark or signpost. It is a short, characteristic melodic phrase that encapsulates the essence of the raga and makes it instantly recognizable.
From a software developer's perspective, you can think of the pakad as a unique hash or a digital signature. It's the most concise representation of the raga's identity.
Let's revisit our two video resources for their definitions of pakad.
Introduction to Hindustani Music | VoxGuru ft. Shivani Mirajkar
The VoxGuru video offers a quick, practical definition of Pakad.
Watch the segment from "we then learn its puckered" where pakad is defined as the "signature phrase of a raga."
Aroh - Avaroh||Pakad||Nyas ke swar|| रागों का आरोह-अवरोह, पकड़, न्यास के स्वर || राग के लक्षण ||
The Soft Music Theory video provides a more detailed Hindi explanation.
Now, watch the section on pakad. The presenter defines it as the smallest group of notes that reveals the identity of a specific raga. He gives the example of Raga Kalyan's pakad and explains that during a performance, this phrase is used repeatedly.
The function of the pakad is crucial in performance. An artist will often return to the phrases of the pakad to establish the raga firmly in the listener's mind and to maintain its emotional atmosphere. It acts as a home base or an anchor.
For example, a common pakad for Raga Bhupali is:
G \ R \ S, \ \ D_{\text{̣}} \ S \ R \ GEven if you heard just this short phrase, an experienced listener would immediately identify the raga as Bhupali.
Conclusion
In this lesson, we have constructed the foundational skeleton of a raga. You now understand that a raga's identity is not arbitrary but is defined by a precise set of rules governing its melodic movement.
Key Takeaways:
- Aaroh and Avroh are the prescribed ascending and descending sequences of notes. They are the mandated pathways for the raga's melody.
- These pathways can be simple and linear (saral) or complex and crooked (vakra), a feature that is essential to a raga's unique character.
- The Pakad is a short, signature melodic phrase that acts as the raga's unique identifier, encapsulating its essence.
- Together, the aaroh, avroh, and pakad form the fundamental grammar that distinguishes one raga from hundreds of others, even those belonging to the same parent thaat.
We have now defined the raga's basic structure. However, this structure is still just a skeleton. To bring it to life and understand its emotional power, we need to add flesh and a heart. In our next lesson, we will do just that by exploring the concepts of vadi (king) and samvadi (minister) swaras. These are the notes that create a raga's hierarchy and establish its emotional center of gravity, a critical step toward understanding how music can be crafted to evoke specific feelings like bhakti.
