Octaves & Axons is an art book by pianist and visual artist Meining Wu, built around a single question: what happens inside us when we hear music? Across twenty-four paintings, drawings, and mixed-media works, sound becomes something you can see. Circuit boards and small lights surface inside canvases, a cochlea opens like a shell, and faces dissolve into waveforms. The titles move between two languages, one borrowed from music and one from the brain, because to Meining they have always described the same thing. Part sketchbook and part field notebook, the collection pairs each work with a short reflection on memory, neurodiversity, and the way every mind maps the world a little differently. Together they form a portrait of a young artist who plays with both hands and thinks with both hemispheres, and an invitation to listen with your eyes. Meining Wu is a concert pianist and visual artist from the San Francisco Bay Area, and the founder of Equal Keys for All, a nonprofit offering free, adaptive piano lessons to under-resourced and neurodiverse children.
