Indian classical arts, including dance, music, and theater, are an example of unity in diversity because they encompass a wide range of regional styles while maintaining shared traditions and values. According to the class 6th social science NCERT, classical dance forms like Bharatanatyam, Kathak, Odissi, and Kathakali, though originating from different regions, follow similar principles of storytelling, rhythm, and expression. Similarly, classical music traditions like Hindustani and Carnatic music have different styles and instruments but are based on common concepts such as ragas and talas. These arts reflect India’s cultural unity, where diverse regional expressions contribute to a shared artistic heritage.
