What Is The Meaning of a "Shruti" ?


 There are 12 universally identifiable notes ('Swaraprakar' in Sanskrit) in any Octave (Saptak). As we play them from one end on any string, the perception of each of these 12 changes 'only' at 22 points given by nature (See red dots below). The sounds produced at these 22 points are the '22 Shrutis' and the 3 types of distances in-between are called as 'Shrutyantara' (in Sanskrit) (See Legend below). 

- Dr. Vidyadhar Oke

Play The 22 Shrutis Yourself !! 



NOTE :

1. You may play 2 shrutis together to experience consonance / dissonance.

2. For playing 22 shrutis in all 12 scales, visit "Hear the shrutis" section.
