Rothko, No. 16

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:

Red: 13%

Black: 30%

Brown: 20%

Background: 37%

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:
