Moving on to the second track, we chose the painting "No. 16" by Mark Rothko:
Firstly, over to Greg to explain how he has converted the image to audio:
"For No. 16 by Rothko, we combined a few different approaches. Because the image is basically four different colours, red, black, brown, and blue, we calculated four chords - one for each colour.
An image is made up of numerous little pieces called pixels - short for picture elements - with each pixel having its own colour. One way of representing a pixel’s colour is using three numbers, a value for the red, blue, and green components of the colour. This is also called RGB.. These three values are combined by the computer into a single colour for display.
For each of the four colours in the image (red, black, brown, and blue), the RGB value for the colour was transformed into a three-note chord (the number next to each letter represents which octave the note belongs to):
Red block: [C4, D3, G1]
Black block: [C4, F3, B3]
Brown block: [A0, G1, E3]
Blue background: [B0, G2, B3]
To determine the length that these chords would be played for we calculated the ratio of each of the block sizes compared to the whole image:
So, the chord derived from the red block plays for 13% of the phrase, the chord derived from the black block plays for 30% of the phrase, and so on.
Finally, we used a similar approach as with the previous piece of music, moving top-to-bottom across the image, to derive a melody."
Back to me. Here's an audio representation of the chords (using my voice as the instrument):
Here's an audio representation of the melody:
The final composition uses the melody and chords as a foundation while expanding on them and adding additional layers. Here's an excerpt of where I'm at with the Rothko track:
