Indian Raag & Frequencies
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.

Musical intervals can be defined in two ways, either by numbers (string lengths, frequencies) or by their psychological correspondences, such as feelings and images they necessarily evoke in our minds. There is no sound without a meaning, so the Indians consider the emotions that different intervals evoke as exact as sound ratios. The feeling of the shrutis depends exclusively on their position in relation to the tonic, and indicates the key for the ragas.
The 22 different keys or degrees encompass what the Indians consider the most common feelings and reflections of the human mind. They were aware of the division of the octave into 53 equal parts, the Pythagorean Comma, and its harmonic equivalent, the comma diesis, (the syntonic comma, the difference between the major and the minor tones).
However, they chose the 22nd division of the octave for reasons based on the limit of human ability to differentiate the keys, as well as for psychological and metaphysical reasons. The symbolic correspondences of the numbers 22 and 7, (7 strings and main notes), could also play a part since the relationship between the circle and the diameter is expressed as the approximate value of Pi, 22/7.
