Fretboard Map vs Classical Guitar Suite

Fretboard Map helps beginning guitarists understand the fretboard visually. Explore the CAGED system, shell voicings, chord tones, and an interactive note map to move beyond open chords and the first three frets. Guided practice paths help you learn roots, octaves, CAGED shapes, and fretboard connections. Hear the notes you are learning with separate recorded acoustic and electric guitar sounds. Play a chord together or hear its tones one at a time as an arpeggio. The acoustic sound uses nylon-string guitar recordings; the electric sound uses pickup recordings with gentle amplifier processing. Both sounds are included for offline playback. Key features: - Diatonic chord diagrams across seven modes, with chord and arpeggio playback - All five CAGED shapes and shell voicings - Triads and major, minor, dominant, and half-diminished seventh chords - Switch between note names and scale degrees - Interactive note learning and guided daily practice - Acoustic and electric guitar playback for notes, chords, and arpeggios - Built-in tuner with 440 Hz, 432 Hz, and 430 Hz reference standards - Landscape layouts for iPhone and iPad - English and Simplified Chinese interfaces No account is required. Build your understanding of chord shapes, note locations, and connections across the guitar neck.

Classical Guitar Suite (CG Suite / formerly ReString Logger) is a comprehensive performance, practice, and instrument maintenance platform designed specifically for classical guitarists[cite: 1]. Note: This application has been rebranded from "ReString Logger" to "Classical Guitar Suite," introducing a fully featured sheet music reader alongside expanded acoustic practice and maintenance tools[cite: 1]. All existing string management, acoustic measurement, and tuning records remain fully supported[cite: 1]. --- Key Features --- 1. Sheet Music Reader (Score Reader) - Fast PDF rendering with seamless page transitions[cite: 1]. - Flexible viewing options: Single page, two-page spread, and a 4-page overview grid[cite: 1]. - Apple Pencil and touch-friendly annotation tools: freehand pens, highlighters, text notes, and musical notation stamps[cite: 1]. - Bluetooth page-turner pedal support with repeat-guard protection[cite: 1]. - Linear sequence builder: set custom cut points to navigate repeats and Da Capo structures in a single direction without jumping back[cite: 1]. - Cloud synchronization via Google Drive to keep scores and annotations securely synced across devices (optional feature)[cite: 1]. - Floating mini-tools: view tuners or metronomes in a compact window over your score while practicing[cite: 1]. 2. High-Precision Strobe Tuner & Acoustic Temperaments - Multi-band phase-accumulating strobe display delivering sub-cent (0.1 cent) visual accuracy[cite: 1]. - Perceptual auto-snap: automatically distinguishes pluck attack transients from stable sustain to confirm true pitch[cite: 1]. - Guitar-specific temperaments: Key-optimized modes to eliminate 3rd-string beat beating, and Chord-optimized modes to compensate for fretting tension rise[cite: 1]. - Dyad Beat Tuning: objective guidance for traditional two-note harmonic and open-string beat listening[cite: 1]. - Automatic string detection across all six strings[cite: 1]. 3. String Management & Guitar Specs - Track days installed, playing hours, tension, and wear across your active guitars[cite: 1]. - Log detailed reviews, string tension specs, and tone profiles for each set[cite: 1]. - Manage inventory for complete sets and individual single strings[cite: 1]. - Comprehensive classical guitar string specification database and comparison tools[cite: 1]. 4. Acoustic Diagnostics & String QA - Objective string quality assurance: measure sustain envelopes, roundness beat modulation, and inharmonicity stiffness (B-coefficient) to detect defective strings[cite: 1]. - 12th-fret octave intonation comparison between natural harmonics and fretted notes[cite: 1]. - Guitar timbre analyzer: track spectral centroid, harmonic balance, and T30 decay times to compare tone evolution over time[cite: 1]. 5. Technique Practice Analyzer & Recording - Real-time analysis for tremolo (p-a-m-i), arpeggios, and alternating scales (i-m): measures strike timing evenness, finger volume balance, and brightness[cite: 1]. - Hands-free studio recorder: auto-arms to start on your first note and auto-stops on silence for instant loop review[cite: 1]. - Acoustic metronome with physical pendulum display and acoustic tempo detection from your guitar playing[cite: 1].
