Harmonium likely to be replaced?

 Fifteen Jathedar continuously sing prayers for twenty hours a day in Swarn Mandir Gurudwara Sahab Ji. Harmonium is a base music instrument on which the tunes for all bhajans are generally created to please and solace the pilgrims coming to bow their heads before the most sacred Granth Sahab Ji source says. Now with the advice of Gyani Harpreet Singh Ji of Akal Takht Sahab, the Harmoniums at Gurudwara Sahab Ji are to be replaced by more original conventional instruments of the country source says. Harmonium is not an Indian instrument, it was brought to the country by English people though till 1915 country was the largest exporter of the instrument because this was adopted by the musicians of the country and the melodious sound attracted music lovers throughout the world source says. It is a basic French instrument used for making tunes for English prayers throughout the world. The change is likely to take at least three years because all new tunes will have to be developed according to the new instrument source says?
