Gharu, ordinarily an equivalent of "house "or "home", here indicates a variant or style of a rdga corresponding to variation in metre, pitch, rhythm and lai. Lai (Sanskrit laya) is a term in Indian musicology signifying timing or speed, Lai figures in three varieties, viz. druta (quick), madhya (mean or moderate) and vilambita (slow). Interestingly, the Sanskrit lay a also means "rest, repose" as well as "a place of rest, residence, house, dwelling," the latter being synonymous with ghar`m Hindi and Punjabi. This explains the use of gharfor musical variations in the Sikh Scripture. In Iranian music, the Persian word gdh (time, place) is used for various musical notes such as dugdh and sihgdh in the same sense.
