01 / THE GUIDE

Guitarbacus basics

One pattern. A whole world of sound.

Guitarbacus is a visual companion for improvising. The fretboard shows a family of notes; the orange notes mark your root, the note that feels like home.

With Mode locked, moving the root shifts the whole pattern into a new key. Switch to Explore modes to keep the same family of notes and choose a different root within it. The pattern stays in place, but the musical center changes.

Drag sideways, use the arrows, or choose a root and mode. You can also tap a fret to choose its note as the root. In Explore modes, only notes in the current family can become the root.

Built for the joy of improvising.

Created by Steven Fenczik, Guitarbacus turns the relationships between notes into a pattern you can explore. Take an idea, pick up your guitar, and make it yours.
