A tala (IAST tāla) means a "clap, tapping one’s hand on one’s arm, or a musical beat." It is a term used in Indian classical music to describe a rhythmic pattern that helps measure musical time. This rhythm is often created by hand clapping, tapping fingers on the thigh, using small cymbals, or playing percussion instruments. Along with raga, which provides the melody, tala gives structure to music and is one of the two main parts of Indian music.

Tala is an old concept from ancient Hindu texts, such as the Samaveda, which included ways to sing religious hymns. Before the 16th century, the music traditions of North and South India were not clearly different. However, during the time when Islamic rulers controlled parts of the Indian subcontinent, these traditions developed into separate forms. The tala system in North India is called Hindustaani, while in South India, it is called Carnaatic. Despite these differences, the tala systems in both regions share many similarities.

In Indian music, tala helps organize rhythm and structure. It does not always mean a repeating drum pattern. In major Indian music traditions, beats are arranged in a specific order based on how a piece is played. The most common tala in South Indian music is Adi tala, and in North Indian music, it is teental.

Tala also has other meanings in ancient Sanskrit texts. For example, it can refer to a type of poetic rhythm called a trochee.

Terminology and definitions

In Indian music, a tala is a system that organizes rhythm. It provides a structure of beats that repeats in a cycle, similar to how meters work in Western music. However, Indian talas have unique features. For example, some talas include many more beats than typical Western meters, such as a cycle with 29 beats that lasts about 45 seconds. Unlike Western meters, which often use strong and weak beats, Indian talas allow for more flexibility. The emphasis on a beat depends on the musical phrase being played, not just a fixed pattern.

A tala divides time into a specific number of beats, ranging from 3 to 128 beats. These beats repeat in a cycle, but the way accents and empty beats are used is an important part of the music’s structure. Each tala also contains smaller repeating patterns, called subunits. These subunits allow musicians and listeners to experience rhythms that align or shift in time. A musician can intentionally change the rhythm at the subunit level, then return to the main cycle.

In classical Indian music, two key elements are the tala and the raga. The raga provides the melodic structure, while the tala offers a framework for rhythmic patterns. When a North Indian tala is played on a percussion instrument like the tabla, the basic rhythmic pattern is called a theka. Each beat in a cycle is called a matra, and the first beat of a cycle is called the sam. An empty beat is called khali. The smaller sections of a tala are called vibhagas or khands. In both major systems of Indian classical music, the first beat of a tala is named sam. The repeating cycle of a tala is called avartan. While both raga and tala allow for endless creative possibilities, the tradition recognizes 108 basic talas as foundational.

History

The roots of tala and music in ancient India are found in the Vedic literature of Hinduism. The earliest Indian thought combined three arts: instrumental music (vadya), vocal music (gita), and dance (nrtta). As these fields developed, sangita became a distinct genre of art, similar to modern music. This likely happened before the time of Yāska (around 500 BCE), since he included these terms in his Nirukta studies, one of the six Vedanga of ancient Indian tradition. Some ancient Hindu texts, such as the Samaveda (around 1000 BCE), are structured entirely around melodic themes. These sections are also found in the Rigveda, which includes music.

The Samaveda is organized into two formats. One part is based on musical meter, and the other on the purpose of rituals. The text includes coded markings, where svaras (octave notes) are written above or within the text, or verses are grouped into parvans (knots or parts). These markings show which sections should be sung in one breath, with each unit based on multiples of one-eighth. The hymns of the Samaveda include melodic content, rhythm, and metric organization. This structure is not unique to the Samaveda. The Rigveda also includes musical meters, though with less detail. For example, the Gayatri mantra has three lines with exactly eight syllables, each containing a three-part rhythm.

According to Lewis Rowell, a professor of music specializing in classical Indian music, the development of mathematically precise musical meters in the Vedic era may have been driven by the need to preserve large amounts of Vedic literature through oral tradition. Systematic structures and meters helped ancient Indians detect and correct errors in memory or transmission between generations.

The Samaveda also included a system of chironomy, or hand signals, to set the speed of recitation. These signals were called mudras (hand postures) and jatis (finger counts of beats), forming the basis of talas. The chants in Vedic texts, used in rituals, were measured in matras and their multiples, following a fixed ratio of 1:2:3. This system became the foundation of every tala.

In ancient Hindu traditions, two musical genres emerged: Gandharva (formal, composed, ceremonial music) and Gana (informal, improvised, entertainment music). Gandharva music was associated with celestial beings, while Gana referred to singing. The Vedic Sanskrit musical tradition spread widely across the Indian subcontinent. According to Rowell, ancient Tamil texts show that a developed musical tradition existed in South India as early as the last few centuries before the Christian era.

The classic Sanskrit text Natya Shastra is the foundation of many classical Indian music and dance traditions. Before the Natya Shastra was finalized, ancient Indian traditions classified musical instruments into four groups based on their acoustic principles (how they produce sound, not the materials used). These four categories are described in four separate chapters of the Natya Shastra: stringed instruments (chordophones), hollow instruments (aerophones), solid instruments (idiophones), and covered instruments (membranophones). Rowell notes that idiophones, such as small bronze cymbals, were used for tala. Much of the chapter on idiophones in the Natya Shastra, written by Bharata, is a theoretical discussion of the tala system. In early Indian music theory, timekeeping with idiophones was considered separate from percussion (membranophones).

The 13th-century Sanskrit text Sangitaratnakara (meaning "Ocean of Music and Dance"), written by Śārṅgadeva and supported by King Sighana of the Yadava dynasty in Maharashtra, discusses ragas and talas. He identified seven tala families, divided them into rhythmic ratios, and presented methods for improvisation and composition that continue to influence modern Indian musicians. Sangitaratnakara is one of the most complete historical Hindu texts on this subject, detailing the structure, techniques, and reasoning behind ragas and talas.

The importance of tala in music during ancient and early medieval India is also shown in temple carvings from Hinduism and Jainism. For example, musicians with cymbals are depicted in the fifth-century Pavaya temple near Gwalior and in the Ellora Caves.

Description

In the South Indian system, called Carnatic, a complete tala is made up of seven types of suladi talas. These are repeating patterns (avartana) divided into three parts (anga), traditionally written using symbols like laghu, drutam, and anudrutam. Each tala is divided in two ways to help organize the musical performance: one way is called kala (kind), and the other is called gati (pulse).

Each full cycle of a tala is called an avartana. This cycle is divided into sections (vibhag or anga), which are similar to musical bars or measures but may not have the same number of beats (matra or akshara). These sections can be marked by accents or pauses. For example, the Hindustani Jhoomra tala has 14 beats, divided as 3+4+3+4, while the Dhamar tala also has 14 beats but is divided as 5+2+3+4. The placement of accents in these sections makes the talas different. However, the Rupak tala, which has 7 beats, would be hard to tell apart from one cycle of Dhamar tala if not for the spacing of accents. The most common Hindustani tala, Teental, is a regular cycle of four measures, each with four beats.

The first beat of any tala, called sam (pronounced like the English word "sum"), is the most important and is strongly emphasized. It is the point where musical phrases end, such as when a soloist plays a key note of the raga or when a dance composition finishes. Melodies may not always start on the first beat of the tala but can begin later to match the rhythm of words in a song. In Tamil, this shift is called talli. A composition might also start with an anacrusis, which is a note played before the first beat of a cycle, called ateeta eduppu in Tamil.

The tala is shown visually through rhythmic hand gestures called kriyas, which match the sections (vibhag) of the tala. In Carnatic music, these movements define the tala. In Hindustani music, the first beat of a section is called tali and is shown by clapping, while an empty section (khali) is shown by a sideways hand wave or placing the back of the hand on the palm of the other hand. Northern traditions often use drum strokes called bols, which have names that can be spoken or written. In one system, the sam is shown with an "X," and the khali, which is always the first beat of a section, is shown with a "0."

A tala does not have a fixed speed (laya) and can be played at different tempos. In Hindustani music, a typical raga performance is divided into parts based on speed: Vilambit (slow), Madhya (medium), and Drut (fast). Carnatic music adds two more categories: Chauka (one beat per stroke), Vilamba (two beats per stroke), Madhyama (four beats per stroke), Drut (eight beats per stroke), and Adi-drut (16 beats per stroke).

Both northern and southern Indian classical music have developed many talas over time, though some are used often, and others are rarely played.

In Carnatic music

Carnatic music uses different systems to classify tālas (rhythmic cycles). These include Chapu (4 talas), Chanda (108 talas), and Melakarta (72 talas). The Suladi Sapta Tāla system (35 talas) is also used. This system divides tālas into seven families. Each tāla in this system must be connected to one of five jatis, which are defined by the number of beats in the laghu (a rhythmic unit). By combining these families and jatis, there are 5 × 7 = 35 talas. These talas have lengths ranging from 3 (Tisra-jati Eka tala) to 29 (Sankeerna-jati Dhruva tala) aksharas (units of rhythm). The seven tāla families and the number of aksharas for each of the 35 talas are as follows:

In practice, only a few talas are used for compositions. The most common tala is Chaturasra-nadai Chaturasra-jaati Triputa tala, also called Adi tala (meaning "primordial" in Sanskrit). Nadai refers to the subdivision of beats. Many kritis (compositions) and about half of the varnams (vocal pieces) are set to this tala. Other common talas include:

• Chaturasra-nadai Chaturasra-jaati Rupaka tala (or simply Rupaka tala). Many kritis are set to this tala.
• Khanda Chapu (10 beats) and Misra Chapu (14 beats), which do not fit neatly into the Suladi Sapta Tāla system. Many padams (lyrical pieces) are set to Misra Chapu, and some kritis use both Khanda and Misra Chapu.
• Chatusra-nadai Khanda-jati Ata tala (or simply Ata tala). About half of the varnams are set to this tala.
• Tisra-nadai Chatusra-jati Triputa tala (Adi Tala Tisra-Nadai). A few fast-paced kritis are set to this tala. This tala has a 24-beat cycle, and some compositions are sung in Rupaka tala.

There are six main angas (rhythmic strokes) in talas:

• Anudhrutam: One beat, notated "U," involves a downward clap with the palm facing down.
• Dhrutam: Two beats, notated "O," includes a downward clap with the palm facing down followed by a downward clap with the palm facing up.
• Laghu: A variable number of beats (3, 4, 5, 7, or 9), depending on the jati. Notated "l," it involves a downward clap followed by counting from the little finger to the thumb and back.
• Guru: Eight beats, notated "8," includes a downward clap followed by a clockwise hand movement with closed fingers.
• Plutham: Twelve beats, notated "3," includes a downward clap, counting from the little finger to the middle finger, a krishya (waving the hand left four times), and a sarpini (waving the hand right four times).
• Kakapadam: Sixteen beats, notated "x," includes a downward clap, counting from the little finger to the middle finger, a pathakam (waving the hand upward four times), a krishya, and a sarpini.

Each tala incorporates one of five jatis. Each tala family has a default jati:

• Dhruva tala: Chaturasra jati
• Matya tala: Chaturasra jati
• Rupaka tala: Chaturasra jati
• Jhampa tala: Misra jati
• Triputa tala: Tisra jati (Chaturasra jati is also called Adi tala)
• Ata tala: Khanda jati
• Eka tala: Chaturasra jati
• For all 72 Melakarta talas and 108 talas: Mostly Chaturasra jati

For example, one cycle of Khanda-jati Rupaka tala includes a two-beat dhrutam followed by a five-beat laghu, totaling seven aksharas. Chaturasra nadai Khanda-jati Rupaka tala has seven aksharas, each four matras (subunits of rhythm) long. Each avartana (cycle) of the tala is 4 × 7 = 28 matras long. For Misra nadai Khanda-jati Rupaka tala, it would be 7 × 7 = 49 matras.

The number of matras in an akshara is called the nadai. Nadai can be 3, 4, 5, 7, or 9, matching the names of the jatis. The default nadai is Chaturasra.

Sometimes, pallavis (melodic sections) are sung as part of a Ragam Thanam Pallavi performance in complex talas. These are called nadai pallavis if sung in non-Chatusra-nadai talas. Pallavis are also often sung in chauka kale (slowing the tala cycle by four times), though this practice is less common now.

Kāla refers to changes in tempo during a performance. Onnaam kaalam is the first speed, Erandaam kaalam is the second speed, and so on. Erandaam kaalam fits twice as many aksharas into the same beat, doubling the tempo. Sometimes, Kāla is used similarly to Layā (rhythm), such as in Madhyama Kālam or Chowka Kālam.

In Hindustani music

Talas can be spoken and written down, with each beat shown as sounds that represent how the tabla is played. Different Gharanas, which are styles of the same art with unique traditions, prefer certain talas. For example, the Kirana Gharana often uses Ektaal for slow songs, while the Jaipur Gharana prefers Trital. Players from the Jaipur Gharana may also use Ada Trital, a version of Trital to help move from slow to fast rhythms.

The khali section has no beats on the bayan, meaning no heavy, low sounds. This helps balance the use of heavy and light sounds or serves as a way to remember the rhythm cycle, along with the strong starting beat called Sam. The khali section is played with a clear, strong sound that stands out from the other beats.

Some talas include a "half-beat." For example, Dharami has 11.5 beats, with the final "Ka" lasting only half as long as the others. The sixth beat in this tala has no sound, similar to a pause in music.

Certain talas, like Dhamaar, Ektaal, Jhoomra, and Chautala, work well with slow or medium speeds. Others, such as Jhaptal or Rupak, are better suited for faster rhythms. Trital or Teental is very popular because it sounds good at both slow and fast speeds. The strong starting beat (Sam) is marked with an "X," the khali section with a "0," and other parts with numbers starting at "2." Some sources say Rupak tala begins with the khali section, making it the only tala to do so.

There are many talas in Hindustani music. Some of the most popular ones include:

72 melakarta talas and 108 anga talas

Compositions are not common in the 108 long anga talas. They are mostly used when performing the Pallavi part of Ragam Thanam Pallavis. Some examples of anga talas are:

Simhanandana tala: It is the longest tala.

Another type of tala is the chhanda tala. These talas are based on the lyrics of the Thirupugazh by the Tamil composer Arunagirinathar. He is said to have written 16,000 hymns, each in a different chhanda tala. Of these, only 1,500–2,000 are still available.
