This is a very interesting passage about two primary art forms: painting and music. In my past knowledge and practice, painting and music, two are parallel. And when we do live coding which combines graphics and music, there is a slight overlap between the two. Specifically, we just try to reflect the rhythms or beats on the graphics while the graphics may have similar themes to the music we make. This passage tells that painting, and by extension, our images can be another form of musical expression and vice versa.
This leads me to think about what kind of combination of graphics and music we are supposed to make. If we only want to make Algorave, it is a good way to use featured themes on both graphics and music, and let the graphics follow the beat or rhythms to change. Because one of the main purposes of Algorave is to make the audience dive into the beats and rhythms, using graphics to visualize the music and the beats of music are always good to use. But when we want to make something more artistic, with the combination, we probably need to change the starting point. Though it’s not the only way to do so, it must be one of the best ways, which is implied in the passage, is keeping the graphics and music parallel. Certainly, it’s not simply parallel. The parallel should be mirror-image relation, or say, the music and image should be doppelgangers of each other. The two can have their own different motives, and the two are interconnected in some ways to present together.
