The people who want to learn about Indian music theory, must know the meaning of Aarohi and Amrohi. It has been described below:

Arohi:

Normally no song or melody goes beyond three octaves (Sabtak). The Octave is called “Sabtak”. in Indian Music. Now three Octaves are, Lower octave, Middle octave and the High Octave.
As you know one octave consists of seven notes (C-D-E-F-G-A-B) so arohi means to play from middle towards the high octave i.e. to play CDEFGAB.

Amrohi:
Amrohi means to play in the reverse order. From high towards low octave. So this means, In Arohi we move upwards whereas in Amrohi we move downwards.
In present day Indian music, the composition of melodies depend on Arohi and Amrohi.

It must be understood that Arohi and Amrohi are different for Raag (we will describe it later), whereas it is different for (Taan) we will know about Taan later on too, at present we are only learning about Arohi and Amrohi.

It is important that while playing any Raag the person has to follow the principle to move up in sequence and similarly play downwards in sequence too as mentioned earlier but there are two form of Raags. One is in which all seven notes are used while in the other some notes are skipped over to left.

First form is called (Shuud) in music language which means in sequence whereas the name of other form is (Vikar) which means not in sequence but in skipped over manner.

In “Taan” the singer only shows the formation of notes in different manner on which the “Raag” is based. The expert or experienced, classical or semi classical Indian singers can perform many beautiful formations of “Taan” of the Raag in all three octaves i.e. base, middle and high. Now I will describe something extremely important as under:
Shuud Thaat

The Indian music theory is purely based on “Thaat”. All the “Raag” evolve from Thaats, that means the entire music theory is based on Thaats. In fact thaat provides the base to know about the notes to be used in specific Raag. We will describe all the Thaats one by one so that the students may know and grasp deeper knowledge.
