Flamenco Warrior is built to be usable by everyone: headings in strict order, controls you can reach and operate from the keyboard with a visible focus ring, text that scales with your browser, and colour that never carries meaning on its own.
The chord charts and fretboard maps get particular attention, because they are where the site does its explaining. Every chord diagram carries its name and its tones as text, every scale map marks its roots with a shape as well as a colour, and every chord and scale can be played back so you can check it by ear. The fretboard explorer announces its changes to a screen reader rather than only redrawing.
