DHUNI, from Skt. dhvani meaning sound, echo, noise, voice, tone, tune, thunder, stands in Punjabi generally for sound and tune. In the Guru Granth Sahib, the term appears in the sense of tune at the head of 9 of the 22 vars (odes) under different ragas or musical measures. Directions with regard to the tunes in which those vars were meant to be sung were recorded by Guru Arjan when compiling the Holy Book. The classical system of Indian music had well established tunes and corresponding prosodic forms; but the var, being basically a folk form, did not have any prescribed order.
VAR, a verse form in Punjabi popular in folklore as well as in refined poetry. In the old bardic tradition of the Punjab, var meant the poem itself with its typical theme as also the form in which it was cast. The earliest vars were ballads of battles and dynastic feuds, of issues of honour fought at the point of the sword and of romantic love. The Gurus employed this form for spiritual themes. The var in Punjabi has since acquired a predominantly Sikh character, though the content subsequently changed from spiritual to heroic.
VARAN BHAI GURDAS is the title given to the collection of forty vars or "ballads" written in`Punjabi by Bhai Gurdas (d. 1636) much honoured in Sikh piety and learning. These forty vars comprise 913 pauris or stanzas, with a total of 6,444 lines. There is no internal or external evidence available to determine the exact time of the composition of these vars, but it can be assumed that vars (Nos. 3,11,13,24,26,38,39) which have references to Guru Hargobind who came into spiritual inheritance in 1606 after the death of Guru Arjan, his predecessor, might have been composed sometime after that year, and the others implicitly prior to that date.
