01. The Classical Concert Harp & Color-Coded String Pedagogy
The modern concert grand harp is one of orchestral music’s most expressive chordophones, commanding a majestic dynamic range from delicate whispering harmonics to sweeping symphonic glissandi. AureliaHarp reproduces a 24-string concert and lever harp layout spanning over 3 octaves (from C3 up to D6).
To support both beginners and experienced harpists, AureliaHarp strictly implements the international Salvi/Lyon & Healy pedagogical color standard:
- Red Strings: All C notes (C3, C4 middle C, C5) are dyed rich crimson red, providing immediate landmark recognition.
- Black / Dark Blue Strings: All F notes (F3, F4, F5) are dyed cobalt blue/black, framing the diatonic tritone interval.
- Amber / Natural Strings: Intermediate notes (D, E, G, A, B) appear in translucent natural gut amber.
02. Real-Time Physical Acoustic Modeling in Web Audio
Rather than playing static audio samples that sound repetitive, AureliaHarp synthesizes each plucked note in real time using the native Web Audio API:
- Pluck Attack Transient: An impulsive burst of filtered white noise models the finger pad or plectrum slipping off the string.
- Additive Harmonic Decay: 4 to 6 harmonic partials resonate with exponential decay rates inversely proportional to string frequency and body damping.
- Soundboard Body Resonance: 4 distinct acoustic wood profiles (Concert Grand Maple, Celtic Spruce, Gothic Mahogany, Warm Walnut) reshape the formant curve.
- Speaker Presence Boost: A dedicated psychoacoustic harmonic exciter designed to project rich harp bass and mid frequencies on phone and laptop speakers.
03. Guided Practice, Repertoire Library & Chord Pads
AureliaHarp includes interactive tools designed for musical discovery and practice:
- Guided Repertoire: Learn classical masterpieces note-by-note with visual glowing string targets, streak counters, and Wait-for-Note practice.
- Arpeggio Chord Pads: Trigger rolled 7-string chords (C Maj, G Maj, A Min, F Maj, E Min, D Min) with customizable rolling arpeggio speeds.
- Symphonic Glissando: Sweep upward or downward across the entire soundboard with one click or touch drag.
