RGB MusicLab is software written by Kenji Kojima that I came across while looking for a RGB/Hex color converter—a plug-in app that Kojima also wrote. The RGB MusicLab software turns pixels into music by assigning each RGB pixel a harmony of three notes. Pixel brightness drives the length of the note.

A score is composed by an algorithm written into the RGB Musiclab software. The software is downloadable as freeware from Kojima’s website. It can be applied to any RGB image and has even been used for a score in a television series.
