Learn the guitar fretboard with focused drills, interactive theory, and practical tools for understanding notes, intervals, chords, modes, progressions, rhythm, and ear training. Fretlight is built for guitarists who want real fretboard fluency: knowing where the notes are, how music theory maps onto the neck, and why the shapes you play actually work. Instead of a video course or a subscription library, Fretlight gives you a clean practice space for building the skills you use every time you pick up the guitar. Practice with targeted drills: - Note Finder: learn every note on every string - Intervals: identify the distance between notes - Chord Builder: build chords from their interval formulas - Triad Builder: practice triads and inversions across the neck - Mode ID: recognize the 7 modes by their notes - Progressions: connect chords to scale degrees and harmonic function Use built-in tools: - Fretboard Explorer: tap the neck to hear and locate notes - Rhythm Trainer: strengthen your internal clock - Ear Training: identify notes by pitch - Metronome: practice with tap tempo and time signature control Study theory visually: - Modes - Chords - Keys - Triads - Circle of Fifths - CAGED System Every reference is designed around the guitar neck, with interactive fretboard diagrams and playable examples that help theory become something you can see, hear, and use. Customize the app for the way you play: - Standard, Drop D, D Standard, Open G, Open E, and DADGAD tunings - Left-handed mode - Reversible string order - Optional string numbers - Fretboard skins - Adjustable sound type - Haptic feedback - Daily practice reminders Fretlight is for beginners building their first reliable map of the fretboard, and for intermediate players who want chords, modes, triads, and progressions to feel less abstract. Open the app, choose a drill, and build the kind of fretboard knowledge that makes practice, improvisation, songwriting, and learning songs easier.
