Ragas of the Guru Granth Sahib

The Guru Granth Sahib, the central scripture of Sikhism, is organized not by book or chapter in the manner of most world scriptures but by raga, the melodic framework native to North Indian classical music, with its many hymns grouped under thirty-one classical ragas presented in a fixed sequence across the text. Each raga section gathers together hymns composed by different Gurus and by the Bhagats, devotional poets from other traditions whose compositions the Gurus included, unified not by author or historical period but by the musical mode in which they were composed and are meant to be sung, so the scripture's structure is fundamentally a musical one layered beneath its devotional and theological content. This organization reflects the conviction, central to Sikh practice, that the Gurus composed their hymns specifically to be sung rather than merely read, each raga chosen deliberately for how its particular melodic character and associated mood serve the meaning and devotional purpose of the hymns set within it.

Performing kirtan, the singing of these hymns in their assigned raga, is accordingly not treated as an optional musical accompaniment to the scripture but as the intended and fullest way of engaging with it, a distinction that shapes how Sikh worship services are structured around live or recorded musical performance of scripture rather than silent or spoken reading alone.

Maintaining an accurate performance tradition for thirty-one distinct classical ragas across a scripture of this scale is a substantial undertaking, and the lineage of ragi musicians, those trained specifically in Sikh kirtan performance, has historically carried this knowledge forward through direct oral and practical transmission from teacher to student rather than through musical notation alone.

Some of the ragas specified in the Guru Granth Sahib are rare or have fallen out of common use in the wider North Indian classical tradition outside Sikh devotional contexts, which has made gurdwara musical institutions and specialist training academies an important, and in some cases the primary, remaining site where the correct performance of certain ragas is actively preserved and taught.

In recent decades this concern has prompted organized efforts, including dedicated kirtan training academies and recorded reference performances, aimed specifically at ensuring the scripture's raga assignments continue to be performed accurately as fewer musicians train in the full classical raga system on its own terms. The tradition also accommodates regional and lineage-based variation in exact melodic interpretation within a given raga, so two ragi performing the same hymn in the same designated raga may render it audibly differently while both remaining within the bounds of that raga's defining structure, a flexibility characteristic of North Indian classical music generally rather than unique to its Sikh devotional use.
