Maple Leaf Rag by Ellen Banks
I find this book intriguing because what Banks is doing is replacing symbols that represent musical notes--which is its own symbolic language--with other geometric symbols to then represent those aforementioned musical symbols. In this way, Banks makes Maple Leaf Rag more accessible to those who don't know how to read music, due to the geometric aspects of the notes that she's translated. For those who don't know how to read music, they may not be able to recognize, for example, the symbol that represents a half-beat while reading music, but they can read the visual relationship between the triangles and the squares.
However, it is difficult, as a reader, to recognize what the colors specifically represent without some prior knowledge of music.Banks states that the color red (I'm assuming that it comes out more pink on the paper) denotes the key of Maple Leaf Rag. Due to the fact that some of Banks' readers will have musical background and some will not, it is entirely possible for each reader, or viewer, to have a different experience with the visual text, either attempting to read the colors and shapes as notes and tones that guide the music, or perhaps seeing those visual symbols in a completely different way, devoid of musical knowledge.
