About This Launch
FretPrism is a free browser-based guitar learning tool that maps scales, modes, chords, arpeggios, and connected recurring patterns across the entire fretboard. It also supports alternate tunings so players can understand note relationships anywhere on the neck.
Why I Built This
FretPrism was built to make fretboard relationships easier to see. Instead of learning isolated boxes, guitarists can explore how scales, modes, chords, arpeggios, and recurring patterns connect across the full neck.
