 | | Rags are defined by the notes used in the scale, but some rags use the same notes yet are recognized as different, so scale alone is not the only feature that separates them. |
 | | In the 20th century, some of the important factors which define rags are That, or mode, Jati, or scale permutation, Prahar, or time of day, and Gharana, or the musical tradition in which any musician may have been trained. |
 | | According to this theory, a rag may have 5, 6, or 7 notes in ascent and 5,6, or 7 notes in descent. |
