Melody is based on our ability to hear and perceive changes in frequencies. Although it is more than just the pitch going up and down, but as the frequency goes higher, the note is sharper. In any octave, the highest note always vibrates at the double rate from the lowest note. So an octave is the interval between one musical note and another with half or double its frequency. After the unison, (two things vibrating at the same rate), the octave is the simplest interval in music. The human ear tends to hear both notes (upper and lower) as being essentially ‘the same’. For this reason, notes an octave apart are given the same name in Indian music. The same is true for Western Music. And just like in western notation system, Northern Indian music recognizes 12 places in one octave as Notes. Most musicians use the same notes as we see them on a guitar’s fret or on a piano (equal temperament scale). But it hasn’t been always like this. In ancient times, Indian music was based on the ‘Sharuti’ system. The intervals were measured with sharuties. We will discuss this in Advanced Theory.

Melody of Northern Indian Music is based on the ‘Thaat’ (parent Scale) and ‘Raag’ theory. Raags have their minimum requirements of five notes in an octave. Based on that principle, 484 Raags can be created mathematically from any given ‘Thaa’t’. We will discuss Thaats and that theory in another post.

Every Raag has its own personality. There are many special things about every Raag, which make it possible to separate one Raag from another. I will explain these in the ‘Properties of a Raag’ post.

Even though many popular musician do not study Raags and most of the popular music is not even in any certain Raags, there are many ‘phrasing’ secrets hidden in the Raags, however. Ascending and descending do not make music. Whole art of music is hidden in phrasing. You must have listened to hundreds of songs composed in ‘C’ or ‘E’ major. They still sound different from one another. That is because music we hear affects us in phrases, not scales.

This theory (music in phrases) was the origin of Raags. Raags start with that in mind and grow from there. To learn a Raag you have to learn its ascending or descending etc., but you also must know its flow and important phrases. There are thousands of available lists of hundreds of Raags everywhere, but they have no practical value as one will never know how to proceed from there. A Raag description without its phrases and flow is useless. I am a working composer. I am giving you the only information that is essential to ‘know and play’ Indian music in the real world. I will post the Raags complete with this data. You will find yourself improvising in a certain Raag in no time by mixing and shuffling its phrases and flow.
