After his scale was demonstrated, Bharatamuni observed that if the Shadja was serially shifted to other notes, groupes of specific notes with a melodic flavour different than the original scale became available. There were 7 notes (S, R1, g1, M1, P2, D1, n1) in the Shadja Grama, and 7 notes (S, R1, g1, M1, P1, D1, n1) in the Madhyam Grama. Thus, Shadja could be shifted on 7 + 7 = 14 notes. He thus described 14 melodic patterns and called them "Moorchhanas". In Sanskrit, the word 'Grama' means a 'group' and 'Moorchhana' means 'upward movement of a musical note'.
The 14 Moorchhanas thus described by Bharata are as below.
