The Guru Granth Sahib is organized by musical mode: its 1,430 pages are arranged into thirty-one ragas, each with an assigned emotional character, and the hymns were composed to be sung in them. That structure means the scripture is not fully encountered when read silently — kirtan, sung with harmonium and tabla, is the intended form. Professional ragis lead it, congregations join, and the practice is common ground between otherwise differing Sikh communities.
