Classical Indian music is a rich and diverse tradition that has evolved over thousands of years. It is primarily divided into two main styles: Hindustani music from the northern regions and Carnatic music from the south. Both styles emphasize improvisation and the use of intricate melodies, known as ragas, which are designed to evoke specific emotions. In classical Indian music, rhythm plays a crucial role, often structured around complex patterns called talas. Musicians typically perform with traditional instruments such as the sitar, tabla, and veena, and vocalists may use a range of techniques to express the nuances of the music.
