Composition

The entire Guru Granth Sahib is written in the Gurmukhi script, which was standardized by Guru Angad in the 16th century. According to Sikh tradition and the Mahman Prakash, an early Sikh manuscript, Guru Angad Dev had taught and spread Gurmukhi at the suggestion of Guru Nanak Dev who invented the Gurmukhi script. The word Gurmukhī translates to "from the mouth of the guru". It descended from the Laṇḍā scripts and was used from the outset for compiling Sikh scriptures. The Sikhs assign a high degree of sanctity to the Gurmukhī script. It is the official script for writing Punjabi in the Indian State of Punjab.

Gurus considered divine worship through shabad kirtan as the best means of attaining that state of bliss – vismad – which resulted in communion with God. The Guru Granth Sahib is divided by musical settings or rāgas into 1430 pages known as ang s "limbs" in Sikh tradition. It can be categorized into three sections:

The word raga refers to the "color" and, more specifically, the emotion or mood produced by a combination or sequence of pitches. A rāga is composed of a series of melodic motifs, based upon a definite scale or mode of the seven svara psalmizations, that provide a basic structure around which the musician performs. Gurbani raags are not time dependent.

Following is the list of all sixty rāgas under which Gurbani is written, in order of appearance with page numbers:
