To be honest, it initially struck me as absurd, the thought of creating a soundtrack for a novel, let alone my own novel-in-progress.
After all, a book is, well, a book. It is static and non-visual beyond the fact of seeing a print or e-book’s typewritten words.
To me, it made little sense trying to apply techniques used in visual arts (most notably motion pictures) to a format that most definitely isn’t a picture (this despite the fact that very good books can indeed succeed in creating vivid pictures in the reader’s mind).
