Raga or Raaga is a concept of melodic frameworks in the Indian classical music tradition. It is a key element in the structure and expression of Indian music, both in the Hindustani (North Indian) and the Carnatic (South Indian) systems. A raga is more than a scale or a melody; it is a complex structure of musical rules and a set of motifs, phrases, and ornamentations that provide a basic template for improvisation and composition.

Definition and Characteristics

A raga is defined by a set of rules including a specific scale or a set of notes, a particular order in which these notes can be used, specific notes that need to be emphasized or avoided, and characteristic motifs or phrases. Each raga is meant to evoke a specific feeling or mood in the listener, which is considered its rasa. This emotional aspect is central to the performance and appreciation of a raga.

Structure

The structure of a raga is built around its ascending and descending scale patterns, known as Arohana and Avarohana. These scales not only define the notes that are to be used but also outline the framework within which the performer improvises. The performance of a raga evolves through several stages, starting with the Alap (a slow, improvisational introduction that explores the notes and mood of the raga), followed by the Jor (a more rhythmic section without percussion accompaniment), and culminating in the Gat or Kriti (a composed piece with fixed lyrics and rhythm, accompanied by percussion).

Types of Ragas

Ragas can be classified into various categories based on different criteria such as the time of day they are traditionally performed (e.g., morning ragas, evening ragas), the season they are associated with, or their emotional or thematic content. Some well-known ragas include Raga Bhairav, Raga Yaman, and Raga Kafi in Hindustani music, and Raga Kalyani, Raga Todi, and Raga Bhairavi in Carnatic music.

Performance

The performance of a raga is highly improvisational, allowing the musician to express individual creativity within the framework of the raga's rules. This improvisation takes place within the context of a tala or rhythmic cycle, and the interaction between the melody and rhythm is a key aspect of the performance. The main performer is usually accompanied by one or more melodic instruments (such as the sitar, sarod, or violin), a drone instrument (like the tanpura), and percussion (such as the tabla or mridangam).

Cultural Significance

Ragas hold a significant place in Indian culture, reflecting the diverse spiritual, emotional, and artistic expressions of the subcontinent. They are not only central to the performance of classical music but also influence other music forms, including film music, folk music, and contemporary fusion genres.

Learning and Transmission

The learning and transmission of ragas have traditionally been through the Guru-Shishya Parampara, a system of mentorship where knowledge is passed down orally from teacher to student. This method emphasizes the importance of direct, personal transmission of the nuances of each raga, which can be difficult to capture in written or recorded form.
