Koes Plus
Today, in Indonesia, at any hour, anywhere, we can hear music, played from just one source or from many sources, as in the village for example, or in the big cities, namely in shopping centers, or cassette/CD shops. We can hear pop music, rock music, heavy metal music, keroncong music, dangdut music, traditional music, western music, etc. Music can be heard in so many forms and places throughout Indonesia, broadcasted routinely from commercial television and radio stations, not to mention in private homes. Music is so pervasive and it is difficult to escape it in our daily lives. Music in general and pop music in particular, lives 24 hours a day. Pop star posters are displayed in the cities and in the villages, in the room of teenagers and of others not so young. Shops owners and roadside traders get opportunity to sell posters of pop idols in various poses, on calendars, exercise book covers, match boxes, and so on. The development of diatonic music (Western music) has been so long existing in Indonesia, especially since the advent of Portuguese and Dutch around 17th century to Indonesia. Since that time the influence of western music kept flowing to Indonesia.
