It is not easy to provide an introductory overview of what a fractal is and how it can be constructed; it is even more difficult to present a possible program that can interpret the geometric properties of a fractal and turn them into music. In this sense, the paper is a very interesting achievement. It offers the preliminary knowledge necessary to understand some of the geometric properties of fractals, and then describes a program that can draw the fractal under a function related to the behavior of the iterating orbits, while other functions translate the color gradients and the pixel positions into a possible sound interpretation that can be called fractal music.
Tanasie et al. do not offer the pseudocode for the translation of images into music, only a very general description, but surely such a program cannot be unique; to produce music, many other programs can interpret the rendered image into acoustic patterns that can be arranged into harmonic frequencies corresponding to a given musical note, of a given instrument, within certain tessitura.
I am certain this paper can inspire some other researchers or artists to develop their own interpretation of an image into fractal music.
