I choose and reproduce one of the following strategies or techniques is: As an orchestra playing in the traffic. I follow the example Karlheinz Stockhausen Helicopter String Quartet (1995).
He wrote a score for a string quartet whose musicians (in this instance the Arditti Quartet) would each play in a helicopter, while their music would be mixed on the ground by Stockhausen and broadcasted in the concert hall. The helicopter rotors are naturally present.
I imitate his works, collected audio material in the central station and darling harbour. In the central station, I have collected the sound of the train, because the train is my most used transport. In the other hand, in darling harbor, I gathered a band of music and mix them together. In the first half part of the music, I used the band’s sound which is strong to representative sound when the train stop. Over time, the music are more and more weak. The train sound are naturally present.
The Helikopter-Streichquartett (English: Helicopter String Quartet) is one of Karlheinz Stockhausen's best-known pieces…en.wikipedia.org
