Books written in Persian, Urdu, English and Punjabi are replete with history of music including references to some important Sikh musicians and musicologists. However, references to any bards or ragis who sing/sang the Sikh hymns exclusively according to the musical measure or ‘raga’ in which they were written by the gurus, are conspicuous by their total absence. And the situation is compounded by the fact that music rendered in non-classical tunes has been, of late, dominating the scenario. This book is a modest attempt to put to print some inputs that I gleaned about a few stalwarts who meticulously stuck to the respective musical measures in all their renderings. I hope it will be received in the spirit in which it has been written
