Gauri (raga)
Gauri is an India musical raga that appears in the Sikh tradition from northern India and is part of the Sikh holy scripture called Sri Guru Granth Sahib. Every raga has a strict set of rules which govern the number of notes that can be used; which notes can be used; and their interplay that has to be adhered to for the composition of a tune. there are Gouris of the Bhairav, Poorvi and Marwa thats with additional qualifiers such as the Shree-anga Gouri, Bhairav-anga Gouri, Poorvi-anga Gouri and so on. These are not considered ‘big’ ragas. In the Guru Granth Sahib, the Sikh holy Granth (book) there are a total of 60 raga compositions and this raga is the ninth raga to appear in the series. The composition in this raga first appear on ang (page) no. 151. Raag Gauri (ਗਉੜੀ) – Gauri creates a mood where the listener is encouraged to strive harder in order to achieve an objective. However, the encouragement given by the Raag does not allow the ego to increase. This therefore creates the atmosphere where the listener is encouraged, but still prevented from becoming arrogant and self-important. Gauri was used by Guru Nanak, Guru Amar Das, Guru Ram Das, Guru Arjan and Guru Tegh Bahadur.
