How many regions are Asian music divided into? Let's talk about the environment of each region first, and then talk about the musical style characteristics of each region.

East Asia, Southeast Asia, South Asia, Central Asia and West Asia

Asia is one of the most developed regions of ancient human civilization. Asian traditional music has a long history, and the splendid Asian music culture is an important part of human music heritage, which has had a great impact on the music development of other continents. Asia can be divided into five musical and cultural regions: East Asia, South Asia, Southeast Asia, Central Asia and West Asia. The melody of East Asian music is very rich, with pentatonic scales, various musical instruments, as well as various folk songs, operas, rap and dances. For example, Japanese gagaku, Qin, Zheng and Sanwei Yue Xian, which were absorbed from China's traditional music and then nationalized, Tang Le and country music in North Korea and, of course, colorful national music in China, are all treasures of oriental music art. Southeast Asian music was first influenced by China and Indian culture, and later some countries were influenced by Islam and the culture of the Later Zhou Dynasty. Classical music in Thailand and Indonesia uses seven tones. Large percussion bands are one of the characteristics of Southeast Asian music. The ancient musical tradition in South Asia continues to this day. The melody and rhythm system in Indian classical music has developed to a high degree, with a variety of hungry syllable modes and a unique decorative sound system. Bangladesh is known as the "country of music", and the Indian subcontinent has deep roots in classical music and folk music. Central Asia and West Asia belong to Islamic culture, which adopts chorus scale, while Arab classical music in Central Asia adopts 24 equal-rhythmic scales. The style is soft and cautious. In the process of the formation of Arabic music, ancient Egypt, Persia, ancient Greece and Rome all exerted great influence. Arabic music culture has also influenced the music in northern India and western China.
