Indian Raag & Frequencies, A raga uses a series of five to nine musical notes upon which a melody is constructed.However, the way the notes are approached and rendered in musical phrases and the mood they convey are more important in defining a raga than the notes themselves. In the Indian musical tradition, rāgas are associated with different times of the day, or with seasons. Indian classical music is always set in a rāga. Non-classical music such as popular Indian film songs andghazals sometimes use rāgas in their compositions
As mentioned above, Indian music, like Western music, recognizes seven notes that can be sharped or flatted to get twelve notes within each octave. A flatted note is called komal. A sharped note is called teevra. Indian Note Names
