The strategy I chose is as an abstract mathematical composition that follows the geometry building. the reference I chose is Iannis Xenakis Pithoprakta (1955–56 ) and Metastaseis (1953). Iannis Xenakis is a music theorist, architect and engineer. He is considered an important post-World War II composer whose works helped revolutionize 20th century classical music. Xenakis pioneered the use of mathematical models in music such as applications of set theory, stochastic processes and game theory. Depending on this, he created some geometry building. For example, Metastaseis was inspired by the combination of an Einsteinian view of time and Xenakis’ memory of the sounds of warfare, and structured on mathematical ideas by Le Corbusier. Finally, Xenakis saw the chief difference between music and architecture as that while space is viewable from all directions, music can only be experienced from one. The preliminary sketch for Metastaseis was in graphic notation looking more like a blueprint than a musical score, showing graphs of mass motion and glissandi like structural beams of the piece, with pitch on one axis and time on the other.In Pithoprakta, Xenakis drew an analogy between the movement of a gas molecule through space and that of a string instrument through its pitch range.
Depending on the strategy, I chose a geometry building , Sydney Opera House. Because it is made by a lost of curves and trangles. I use proportional function to draw a drawing. Let x = time and y= pitch, when x= 1sec, y =a1. And then I create a drawing. I went to Sydney Opera House to record a sound about 9 mins. Then I cut the different pitch sounds to put them together depend on my drawing. For example,on 1st sec in my sound, I stochastic choose a part of my original sound ( the 9 mins one), cut the A1 pitch of part. Putting in new sound. Until I finished 40 sec.
I use a lot of circle in my drawing. because I feel my sound is smooth not sharp even it sounds strange. another reason is when I hear this sound I will think ‘UFO is coming’ . And at the end of my sound, the frequency is increasing. So I draw the small circles connect together.
