Welcome to Voicylab!
This app is a creative partner that helps you discover new possibilities on the guitar. It does two main things: finds every possible way to play a chord, and predicts the perfect next chord in a harmonic progression.
🎸 How to Find a Chord Voicing?
Enter 3 or 4 notes of a chord into the large white boxes.
Click Strict Search. The app will find all positions where the notes appear on the guitar in the order you entered them (from the lowest string to the highest).
Click Flexible Search to find all possible positions, regardless of the note order.
Browse through the results with the arrow buttons (< >) to see all the options on the fretboard.
✨ How to Predict the Next Chord?
Set the "rules of the game" in the top controls: Scale, Cycle (the harmonic progression), and Direction (the voice-leading direction).
Enter the four notes of the starting chord into the white boxes.
Click the Next Chord (▶) button.
The app will calculate the next chord in the sequence, update the note boxes, and automatically show you the positions for it on the fretboard.
That's it! We recommend just starting to experiment. Enjoy!
