Design notes
Guitar Wiz has to make specialised musical information legible on a small screen. Chord diagrams, finger positions and tuner feedback turn an abstract sound into something a player can see and act on immediately.
The interface is worth examining for the relationship between diagram and action: clear fretboard geometry, direct feedback and guided practice help users move between looking, listening and playing. Accessibility matters especially here because users often interact while holding an instrument.
