Sundanese Music (Sundanese: ) is an umbrella term that encompasses diverse musical traditions of the West Java and Banten in western part of Java, Indonesia. The term of "West Java" is preferred by scholars in this field. The word "Sundanese" originally referred to western part of Java Island and has a strong association with the highly centralized Sunda Kingdom based on Java Island and its high culture practiced by the nobleman class in its capital Parahyangan. By contrast, scholars who cover a much broader region lay emphasis on folk culture. The people of Sundanese, who inhabit the westernmost third of the island of Java, are sometimes wrongly referred to by foreigners as Javanese. Sundanese culture, language and music are quite distinct from those of the Javanese people of Central and East Java - although of course there are also elements in common. In Sunda there is a bewildering diversity of musical genres, musical composition and tuning systems are recognizably different. In Sundanese music the term musical instrument or musical sound produced in various ways is called Waditra. In Sundanese music, there are several Waditra, namely Waditra Tiup (inflatable), Waditra Takol (beat), Waditra Tepak (tap), Waditra Keset (mat) and Waditra Geter (vibrate).
