Sikh liturgy and music form the ritual and sonic core of the Sikh tradition, encompassing the formal prayers of the daily regimen, the ceremonial reading of the Guru Granth Sahib, and the distinct musical system—Gurmat Sangeet—through which scriptural hymns are sung. The field studies not only the texts and their prescribed performance but also the theological assumptions about sound, embodiment, and community that make these practices meaningful. At its center lies a paradox: Sikhism is a scriptural religion that elevates the spoken and sung word, yet its liturgy is deliberately spare, and its music is governed by a rigorous classical framework that coexists with popular devotional styles.
The Guru Granth Sahib, the eternal Guru of the Sikhs, is both a scripture and a liturgical object. Its 1,430 pages contain hymns (shabads) composed by the ten Sikh Gurus and by Hindu and Muslim saints whose writings were included by the fifth Guru, Arjan, when he compiled the first edition in 1604. The text is organized not by author or theme but by the thirty-one ragas—the melodic modes of North Indian classical music—under which each hymn is to be sung. This structural choice signals that music is not an ornament to the scripture but constitutive of its proper reception. A hymn placed under a particular raga is meant to be performed in that mode, at the appropriate time of day or season, with the emotional and spiritual color that the raga carries.
The daily liturgy, known as nitnem, is fixed and relatively short. Practicing Sikhs recite it in the early morning, evening, and before sleep. The morning portion includes the Japji Sahib (the opening composition of the Guru Granth Sahib, attributed to Guru Nanak), the Jap and Sawayya hymns of Guru Gobind Singh, and the Anand Sahib (the "Song of Bliss" by Guru Amar Das). The evening recitation includes the Rehras, a compilation of hymns from several Gurus, and the night prayer is the Kirtan Sohila, a set of five hymns. These texts are recited from memory or read from a gutka (a small prayer book), and they are understood as a discipline of remembrance (simran) rather than as a congregational liturgy in the Christian or Muslim sense. There is no prescribed congregational prayer for lay Sikhs; the nitnem is individual, though it is often performed in family or sangat (congregational) settings.
The central congregational liturgy is the kirtan—the singing of hymns from the Guru Granth Sahib, usually accompanied by harmonium and tabla, and sometimes by traditional instruments. Kirtan is not a performance in the Western concert sense; it is an act of devotion in which the congregation participates through listening, sometimes joining in the refrain. The ragi (the musician who performs kirtan) is expected to sing the exact words of the scripture, without improvisation of the text, though melodic elaboration is permitted. The theological claim is that the shabad (the Word) is itself the Guru's presence; singing it is a means of merging the mind with the divine Name (nam).
The musical theory governing Sikh hymnody is called Gurmat Sangeet—the music of the Guru's way. It draws on the classical Hindustani tradition of raga and tala (rhythmic cycles), but it is not identical to it. The Guru Granth Sahib's raga headings correspond to a system that was already in flux in the sixteenth and seventeenth centuries, and some ragas named in the scripture are no longer performed in the mainstream classical repertoire. This has created a central problem for the field: how to reconstruct or interpret a musical system whose original performance practice was never notated and whose theoretical treatises are sparse.
Three broad approaches have emerged in response. The first is the traditionalist or ragi lineage approach, which preserves the melodic contours and rhythmic patterns as they have been transmitted orally from teacher to student within Sikh families and institutions. This approach treats the received practice as authoritative, even when it diverges from classical theory. Its strength is continuity; its limitation is that it cannot adjudicate between competing oral versions or recover lost ragas.
The second approach is the classical revivalist movement, which emerged in the twentieth century, particularly through the work of musicians and scholars trained in the Hindustani classical tradition. These figures argued that the Sikh Gurus intended the hymns to be sung in the pure classical ragas, and they sought to correct what they saw as the degeneration of Sikh music into folk or popular styles. They reconstructed the ragas named in the scripture using classical treatises and contemporary practice, and they trained a generation of ragi musicians in rigorous classical technique. This approach has been influential in Sikh institutions and in the standardization of kirtan in the diaspora, but it has been criticized for imposing a later classical orthodoxy onto a tradition that may have been more fluid and regional.
The third approach is the ethnomusicological or historical-critical one, which treats the raga system of the Guru Granth Sahib as a historical artifact to be studied rather than a living practice to be restored. Scholars in this vein examine the raga names in the scripture, compare them with medieval Indian musical treatises, and analyze the melodic structure of the hymns as they are currently sung. They are less concerned with authenticity than with understanding how the musical system functioned in its original context and how it has changed. This approach has produced important scholarship but has had less direct impact on liturgical practice.
These approaches are not mutually exclusive. Many contemporary ragi musicians combine classical training with traditional lineage knowledge, and some scholars also practice. The field is characterized by ongoing negotiation between the claims of textual authority, oral tradition, and classical theory.
Beyond the daily prayers and kirtan, Sikh liturgy includes a set of communal rituals centered on the Guru Granth Sahib. The most important is the akhand path, a continuous reading of the entire scripture, which takes approximately forty-eight hours and is performed by a relay of readers. The sadharan path is a non-continuous reading that may take weeks or months. Both are undertaken on occasions such as births, deaths, and anniversaries, and they are understood as acts of devotion that bring the community into the presence of the Guru.
The ardas is a formal prayer recited standing, usually at the conclusion of kirtan or other ceremonies. It is not from the Guru Granth Sahib but is a fixed liturgical text that summarizes Sikh history and petitions, and it is followed by the congregation's collective response of "Waheguru" (Wonderful Lord). The ardas is performed with the congregation standing and with folded hands, and it ends with the hukam—the taking of a random verse from the Guru Granth Sahib as the day's instruction.
The hukam (literally "command") is a distinctive liturgical act. After the ardas, a ragi or reader opens the scripture at random and reads the hymn at the top of the left-hand page. This verse is then treated as the Guru's directive for the individual or community at that moment. The practice embodies the Sikh belief that the scripture is a living Guru, not a historical document.
The traditional Sikh instruments are the rabab (a plucked lute associated with Guru Nanak's companion Mardana), the sarangi (a bowed instrument), the taus (a peacock-shaped bowed instrument), and the jori (a pair of drums, a precursor to the tabla). These instruments were used in the early centuries of the tradition. In the nineteenth and twentieth centuries, the harmonium (a hand-pumped reed organ) and the tabla became standard in most gurdwaras (Sikh temples), largely because they were portable, loud enough for congregational settings, and adaptable to the melodic style. This shift has been controversial among purists, who argue that the harmonium cannot produce the microtonal inflections (shruti) required by the ragas, and that its fixed pitch limits the singer's expressive freedom. Some revivalist groups have reintroduced the traditional instruments, but the harmonium remains dominant in practice.
Performance practice also includes the dhadi tradition, a distinct genre of Sikh music that is not liturgical in the strict sense. Dhadi musicians sing heroic ballads about Sikh history, accompanying themselves on the dhadd (a small frame drum) and the sarangi. This tradition is associated with the martial and political dimensions of Sikh identity and is performed in gurdwaras and at community events, but it is not part of the formal liturgy.
The relationship between the liturgical text and its musical setting is the central question of the field. In Sikh theology, the shabad is not a meaning-bearing message that happens to be set to music; it is a sonic manifestation of the divine. The raga is understood as a vehicle that shapes the emotional and spiritual state of the listener, preparing the mind for the reception of the Word. This is why the Guru Granth Sahib is organized by raga rather than by author or theme: the musical mode is part of the meaning.
This theological stance has practical consequences. It means that the correct performance of a hymn requires attention to the raga's melodic rules, its time of day, and its emotional character. It also means that the congregation's participation is not passive. The listener is expected to internalize the sound, to let it become the object of meditation, and ultimately to merge with the divine Name. The music is thus not an accompaniment to prayer but a form of prayer itself.
At the same time, the liturgy is deliberately minimal. There is no elaborate ritual calendar, no complex system of liturgical seasons, and no priestly class with exclusive authority. Any Sikh, male or female, who can read the Gurmukhi script may perform the path (reading) or lead the ardas. The ragi musicians are trained specialists, but they are not priests; they are servants of the congregation. This egalitarian structure reflects the Sikh rejection of caste and ritual hierarchy, and it shapes the way liturgy and music are taught and transmitted.
In the present day, Sikh liturgy and music are practiced across a global diaspora, with significant communities in India, the United Kingdom, North America, and Southeast Asia. The institutional centers are the major gurdwaras, which employ ragi musicians and organize kirtan programs, and the Sikh educational institutions in Punjab, such as the Sikh Missionary College and various taksaals (educational seminaries), which train ragi musicians and liturgical readers.
The field is currently shaped by several tensions. One is the tension between standardization and diversity. The classical revivalist movement has pushed toward a uniform, classically rigorous style of kirtan, while regional and family traditions preserve local variations. Another tension is between the traditional instruments and the harmonium, which remains ubiquitous despite scholarly and theological objections. A third tension is between the liturgical use of music and its commercial or popular use. Kirtan has entered the global "world music" market, and some Sikh musicians have adapted hymns to contemporary genres, a development that some regard as a legitimate evolution and others as a dilution of the tradition.
Digital technology has also transformed the field. Recordings of kirtan are widely available online, and many Sikhs learn hymns through YouTube tutorials and mobile apps rather than through formal apprenticeship. This has democratized access but has also weakened the guru-shishya (teacher-student) transmission that was traditionally central to learning the music. The question of how to preserve the integrity of the raga system in the face of these changes is an active concern among practitioners and scholars alike.
The field of Sikh liturgy and music is thus not a static repository of ancient practices but a living, contested domain. Its central questions—how to sing the Word correctly, what instruments to use, who may perform, and how to balance tradition with change—remain open, and they are answered differently in different communities. What unites the field is the conviction that the sound of the scripture is not incidental to its meaning but is the very medium through which the divine communicates with the human.
