What this dot point is asking
SEAB wants you to explain how North Indian classical music is organised around the raga (its melodic framework) and the tala (its rhythmic cycle), supported by a continuous drone, and to recognise its main instruments, the sitar, tabla and tanpura. The central insight is that Indian classical music is improvised within strict frameworks: the raga governs the notes and mood, the tala governs the rhythm, and over a steady drone the musicians create the music live within those rules.
The answer
Raga: the melodic framework
A raga is much more than a scale. It is a framework for melody that fixes:
- a set of notes (which notes are used ascending and descending),
- characteristic phrases and ornaments,
- which notes are emphasised or treated as resting points,
- and an associated mood (and often a time of day or season).
The performer improvises a melody within the raga, so each performance is unique but stays true to the raga's identity.
Tala: the rhythmic cycle
A tala is a repeating rhythmic cycle of a fixed number of beats, grouped in a set pattern. A very common tala has a sixteen-beat cycle. The first beat of the cycle, the sam, is the most important: the music continually returns to it, and players aim to land together on the sam at the end of a phrase. The tala gives the metred music its structure and drive.
The drone
A continuous drone, usually the tonic note and its fifth sounding throughout, anchors the pitch of the whole performance and provides the constant background against which the raga's notes make sense.
The instruments
- Sitar: a large plucked string instrument with movable frets and sympathetic strings, capable of expressive bends (meend); it typically presents the raga.
- Tabla: a pair of hand drums (one for low, one for higher sounds) that play the tala with great rhythmic subtlety.
- Tanpura: a long plucked lute with no frets, played continuously to provide the drone.
The shape of a performance
A performance often unfolds in stages: a slow, free, unmetred opening (the alap), in which the soloist explores the raga over the drone alone; then a metred section when the tabla enters with the tala, after which soloist and drummer improvise, usually increasing in speed and intensity toward a climax.
Examples in context
Example 1. A sitar raga performance. A classic sitar recital opens with a meditative, pulseless alap that gradually unfolds the chosen raga over the tanpura drone, then bursts into life when the tabla enters with the tala, soloist and drummer trading ideas at rising speed. It is the textbook illustration of the alap-to-gat shape and the three-layer texture.
Example 2. A vocal khayal. In Indian classical singing, a vocalist takes the role of the melody instrument, improvising the raga over the drone with the tabla supplying the tala. It shows that the raga-tala-drone framework underlies vocal as well as instrumental performance, the voice presenting the raga in place of the sitar.
Try this
Q1. Explain the difference between a raga and a tala. [2 marks]
- Cue. A raga is the melodic framework (notes, phrases and mood within which the melody is improvised); a tala is the rhythmic cycle (a repeating pattern of a fixed number of beats).
Q2. Name the instrument that provides the melody, the rhythm and the drone in a sitar performance. [3 marks]
- Cue. The sitar provides the melody (the raga), the tabla provides the rhythm (the tala), and the tanpura provides the drone.
Q3. Describe how the texture changes from the alap to the metred section. [2 marks]
- Cue. The alap is two layers (melody plus drone) with no pulse; when the tabla enters with the tala it becomes three layers (melody, drone and rhythmic cycle), and the music usually speeds up.

Original6 marksExplain the roles of raga, tala and drone in North Indian classical music, and name the instrument that typically provides each layer.Show worked answer →
Raga: the melodic framework. A raga is a set of notes (like a scale) with characteristic phrases, rules about which notes are emphasised, and an associated mood; the melody is improvised within the raga. The sitar (or a singer) presents the raga.
Tala: the rhythmic cycle. A tala is a repeating cycle of a fixed number of beats (for example a sixteen-beat cycle) grouped in a set pattern; the music returns to beat one (the sam) at the start of each cycle. The tabla (a pair of hand drums) plays the tala.
Drone: a continuous sustained note (usually the tonic and its fifth) that underpins the whole performance and anchors the raga's pitch. The tanpura (a long plucked lute) provides the drone.
What markers reward: a correct role for each layer, melody framework (raga), rhythmic cycle (tala) and sustained anchor (drone), and the right instrument for each (sitar, tabla, tanpura). The strongest answers mention the sam, the important first beat of the tala cycle.
Original5 marksDescribe the typical shape of a North Indian classical performance, from its free opening to its rhythmic climax, and explain how the texture builds.Show worked answer →
A performance usually begins with the alap: a slow, free, unmetred exploration of the raga by the soloist over the drone alone, with no fixed pulse, gradually introducing the notes and mood of the raga.
It then moves into a metred section (the gat or composition) when the tabla enters with the tala. From here the soloist and drummer improvise within the raga and tala, often increasing in speed, density and excitement toward a climax.
Texture: it builds from a thin two-layer texture (melody plus drone) in the alap to a fuller three-layer texture (melody, drone and rhythmic cycle) once the tabla enters, with the improvisation growing more elaborate over time.
What markers reward: the move from a free, unmetred alap over the drone to a metred, tabla-driven section that accelerates to a climax, and the build from a two-layer to a three-layer texture. The strongest answers name the alap and note the rising speed and intensity.
