FretBored is an interactive virtual fretted instrument. Written in React/Redux, it allows users to specify a number of strings and what notes those strings are tuned to. Given these values, it computes which notes/positions on the fretboard are in any given key or chord, major or minor. It can also calculate positions for custom note groupings. The app renders these positions with an orange marker or a special marker to denote the root/tonic.
