📖 How to Use

Getting Started
FretSense is a comprehensive ear training and theory tool for guitarists.

1. Training & Quizzes
Select a module to visualize the fretboard, or tap Start New Quiz to test your skills (your best streaks are saved automatically):

Scale Finder: Visualize modes/scales and quiz yourself on intervals or notes.
Triad Builder: Drill inversions and muscle memory on specific string sets.
Triad Explorer: Step through inversions and string sets to connect voicings across the neck.
Chord Progression: (No Quiz) Analyze progressions, find modes, and record loops.

2. Loop Recorder
Record your own backing tracks directly in the browser.

Record: Capture your playing (use the visual metronome if needed).
Trim: Use the waveform editor to trim silence. Auto-trim creates seamless loops.
Map: Define your chords, click "Map," and tap along to your recording. The app will sync the fretboard display to your audio!

3. Vibe & Analysis
In Chord Progression mode, use the "Vibe" dropdown to see how theory changes based on genre:

Pop/Bright: Shifts minor keys to relative major.
Sad: Focuses on the b3 and minor pentatonic.
Blues/Rock: Highlights Blue Notes and Pentatonic substitutions.
