Books written in Punjabi, Persian, Urdu, and English are replete with music history, including references to some important Sikh musicians and musicologists. However, references to any bards or raagis who sang the Sikh hymns exclusively according to the musical measure or raaga in which the Gurus wrote them are conspicuous by their absence.\n\nThe situation is compounded by the fact that music rendered in non- classical tunes has dominated the scene of late.This book is a modest attempt to print some inputs gleaned about a few stalwarts who meticulously stuck to the respective musical measures in all their renderings. It is hoped that you will receive the book in the spirit in which it has been written.
