THE TRANSLATION

This picture has no hidden “correct” tune. This is one deliberately chosen way to play it.

Each of the sixteen equal-width columns contributes the average RGB colour of the selected one-pixel row. Those colours set the notes.

brightness = round(0.2126R + 0.7152G + 0.0722B)

Weighted brightness of stored RGB channels, 0–255; not calibrated physical luminance.

0–50C451–101D4102–152E4153–203G4204–255A4

Try black: sixteen low C notes. Try white: sixteen high A notes. Then return to the landscape and move the horizontal line.

See every sample: RGB → brightness → note

Actual sampled values. Notes also work with Enter or Space; arrow keys move between notes.
