Finally I started actually working on my abstraction using PaintTool SAI. I altered the colors of the audio to yellow, to represent the candlelight. I flipped and stretched copies of the image and placed them in a stripe pattern over the canvas to represent the sounds in the air created by the candles.

Next I made a circle shape underneath all the sound as an abstraction of the shape the candles were placed in, and placed black diamonds to represent the locations of the candles and Arduinos. 

The ways in which I layered the representation of the sounds with the abstraction of the visual element of the piece shows how the sound seemed to be the focus.
