Research->Genre Study->Ethnic Music->Indian Music
What is ethnic music? What element distinguishes an ethnic music style from other ethnic music styles? For example, what is the difference between Okinawa music and Scotland music? I think elements of music are (1) melody (scale), (2 ) chord, (3) rhythm, and (4) instruments. 
First, let's think about melody. Rock and Blues are easy examples, even though they are not ethnic music. Rock uses normal music scale while Blues includes blue-notes in its music scale. Next, think about chords. Rock uses simple chords (triad) while Jazz includes 7th in its chords. Chord progression of Jazz is more complicated than that of Rock as well. For rhythm, Rock uses 8 beat, Fusion uses 16 beat, Jazz uses 4 beat. Finally, think about musical instruments. It is easy to see differences between Classical music and Rock music. Especially, musical instruments are important elements of ethnic music, since each country has different music instruments. 
I am trying to capture features of each ethnic music style based on this idea, and to reproduce them with automated composing system. This page includes considerations that I faced when I embedded functions of ethnic music composition.
About Indian music
Indian music Consideration Indian music is divided into several categories according to the geometrical area of India. In this article, I will write about Hindustani music. In this page, I am writing the summary of each music style, although each style is actually much more complicated. Specially, Indian music is far from western music, so please be reminded that the description below is very superficial.
Firstly, Indian music scale is very different from western music scale. Indian music scale has seven notes and they are put in equal interval in an octave while western music scale has twelve notes and they are put in equal interval in octave. These seven notes are called "Sa", "Re", "Ga", "Ma", "Pa", "Dha", "Ni", "Sa." These notes correspond to "C", "D", "E", "F", "G", "A", "B", "C." Hindustani music is improvisation music. The tune is not prepared. Players make melodies for instance. However, there are some rules that vocal artists or instrument players must to follow. These rules are called "raga." Raga specifies music scale and its arrangement. For example, it says "use note C D Eb F G Ab B, and do not play Eb after F. Or, use Eb only when melody line is descending." (This rule is not included in actual raga.) Although music is played following these rules, music is always a new one.
Second, rhythm is called tala which means "parm" or "meter" originally. Tala is a continuous musical cycle. In tala, certain music patterns are repeated. The first beat of tala is called "Sam" and all rhythm pattern and melody variations are resulted at Sam. (Otherwise it can not be cyclic...) 
Lastly, about musical instruments and style of ensemble, typical ensemble consists of "Sitar" and "Tabla." One session of playing consists of "alap" and "gat." At alap, scale and characteristics of raga are introduced. Main player shows each note of raga and an atmosphere is created. Usually, it begins with a part which does not have tempo, and moves to a part which has a certain tempo, then alap ends. When the main player plays main theme with certain rhythmic cycle, it denotes the beginning of later part, gat. In this part, tabla player finds basic tala of the given theme and begins to play basic pattern of tala. In gat, variations of melody and theme are resoluted at certain point by main player, and moves to theme again. When main player goes back to the theme, tabla player begins to improvise on variations of rhythm. Both players repeat this kind of interaction and make tempo faster gradually. Typically, the music goes to another tala and music reaches a climax where both players come to their limit of technique. The players interactions, imitation of partners pattern, changing, and so on brings forth emotional changes on the audiences. 
The automated composing system uses sitar as musical instrument and tries to imitate the wonderful atmosphere of Indian music. The same low pitch is used and sound of sympathetic strings are added. 
Does it sound like Indian music?
