Guitar Chord Chart Maker for Teachers, Songs, and Practice Sheets

Fretboard Lab is a desktop chord voicing workbench for guitarists, teachers, and songwriters who need playable shapes instead of another random chord box. Type a chord or progression, explore positions, compare difficulty, switch tunings, and export diagrams for practice sheets, lessons, charts, or writing sessions.

The problem with ordinary chord charts

Most chord charts answer the smallest possible question: where can I put my fingers for this chord? Real playing asks better questions. Which voicing fits the melody? Which one avoids the bass player's range? Which shape moves cleanly into the next chord? Which option can a student play today? Fretboard Lab is built around those practical choices.

A $19 tool for repeatable arrangement work

The value is not that the app knows a Cmaj7 shape. Free websites already do that. The value is the speed of comparing playable options, filtering by position and difficulty, changing tuning, and exporting clean diagrams without rebuilding the same search every time.

Chord charts should be clean enough to reuse

Teachers and songwriters need diagrams that can live in lesson notes, song folders, and practice sheets. Fretboard Lab helps you choose the voicing first, then export the diagram so the useful choice is not lost after the session.
