About FretWiki
By NIXX Music
What is FretWiki?
FretWiki is a free, interactive fretboard reference tool designed for guitarists, bassists, and ukulele players of all skill levels. Whether you're a beginner learning your first pentatonic scale or an advanced player exploring exotic modes, FretWiki gives you a visual, hands-on way to understand and practice scales across the entire fretboard.
Our Mission
We believe that learning music theory should be accessible, visual, and fun. FretWiki was built to bridge the gap between knowing scale shapes and truly understanding how they connect across the neck. Our goal is to help every musician unlock the fretboard and play with confidence in any key.
