Art in India has existed since ancient times. People from long ago carved rock to create images. Nowadays most people paint on paper or canvas to express personal feelings and religious beliefs. People also used colored flour to create images outside their front doors. This is called "Rangoli". Music is also another aspect of Indian culture. It could be considered material culture and/or immaterial culture depending on how it was passed down. There are two basic styles of classical music in India. The first style originated in Northern India and is the Hindustani musical style. The second type originates in South India and is the Carnatic style of music. Indian pop, rock and jazz music also exists in India today. Clothing is another aspect of material culture. Almost all Indians wear very colorful clothing. The most common thing for women to wear in India is a “Sari”. This is a single piece of colored cloth that is wrapped around the body. Although most Indian clothing looks the same, religion can cause some differences in what women wear. Muslim women are required to wear a "hijab", a scarf-like material that must be worn over their hair
