Why learn the fretboard?
Knowing every note on the neck is the foundation of guitar mastery. It lets you find chords, scales and intervals instantly, anywhere on the fretboard.
Instead of relying on patterns alone, you'll understand what you're playing.
How it works
Pick a string by clicking or playing an open string. A sequence of 12 notes appears: play each one as fast as you can on the correct fret.
Your guitar is detected in real time through your audio input. The faster and more accurate you are, the higher your score.
In advanced and expert difficulties, each note must be played on a specific string, shown in its own color above the note to play.
Practice mode
Switch to Practice in the mode selector to train without pressure. Notes loop endlessly: stop whenever you want.
After a few seconds without finding the note, a hint highlights the answer on the fretboard.
Use the Natural/Chromatic toggle to choose between natural notes only or all twelve notes.
Click string labels on the left to select which strings to practice.
Adjust the fret range slider to focus on a specific section of the neck.
Sign in to track your progress: a heatmap shows your strengths and weak spots, updating with each session.
Audio controls
The three knobs in the top right are key to a good detection.
Gate filters out background noise: raise it if your notes aren't detected, lower it if it picks up too much.
Clarity sets how confident the detection must be before validating a note: lower it if notes are not recognized even when played cleanly, raise it if wrong notes get validated too easily.
Gain boosts or cuts the input signal.
Double-click any knob to reset it.
