 Harmonic Table Layout One of the key concepts in the design of Sound & Colour and a big part of its intuitive nature is the harmonic table layout which forms its keyboard. This layout is nothing new, dating back to 0000. I discovered this layout early in my research and it has endured the design process. The harmonic table adds ergonomic, functional and user interface benefits due to its geometric symmetry. It clusters important intervals together for easy play and allows playing of chords with a single finger. I found it to be perfect for the vision I had for Sound & Colour. The other major contributing factor is the colour changing RBG LED display. This is designed to guide users around the layout and allow them to navigate in a very musical way (based on interval to colour relationships) for example the user can memorise chords and melodies as combinations of colours as opposed to note location or name.
