Tetratonics: The 4th Dimensionはどんなアプリ？
Tetratonics: The 4th Dimensionは、現代ジャズの和声構造を視覚的に捉えながら高度なコード進行を構築するアプリです。
三和音に特定の音を重ねて洗練された響きを作る十種類のパターンから選べるため、理論と実際の音のつながりを整理しながら制作を進められます。選んだスケールに合わせて構成音が自動で調整されるため、複雑な音楽理論を計算することなくスムーズにコードを選べます。視覚的な図解では音の役割ごとに色が分けられており、各音が持つ役割を直感的に把握できる仕組みです。複数の楽器を重ねた状態での試聴も行えるため、実際に耳で確認しながら理想の響きを探せます。
複雑な和声構造を追求する作曲家や編曲家が、理論を具体的な音に落とし込む際に活躍します。自分の好みのコードを保存していつでも呼び出せるため、創作のインスピレーションを形にする場面で役立ちます。

WELCOME TO THE FOURTH DIMENSION: TETRATONICS 2.0 IS LIVE!
What was once a silent visual calculator is now a high-fidelity, playable, tactile instrument. Version 2.0 transforms Tetratonics into a professional, zero-latency harmonic laboratory. We have rebuilt the entire app from the ground up around a dual-sampler AVAudioEngine to let you play, layer, and orchestrate modern jazz harmony in real time.
Here is the complete, high-fidelity breakdown of everything new in Version 2.0:
--- THE SOUND STUDIO ---
Step into a glassmorphic control room. Rebuilt as a unified three-tab panel, the Sound Studio lets you sculpt every detail of how your harmony is arranged and performed:
- TETRATONIC TAB (Melody): Sculpt the upper structures. Drag-and-drop to reorder scale pitches into custom licks, apply 7 geometric arpeggio patterns (Ascending, Descending, Pendulum, Arc, Resolve Up, Resolve Down, Block), and slide note timing from driving to loose.
- CHORD TAB (Harmony): Voiced with 8 gorgeous pads. Select from 6 classic voicings, 3 articulation styles, and 4 velocity contours visualized as live sparklines.
- MIX TAB: Independently balance the volume of the chord and tetratonic layers from 0% to 100% of your device's full dynamic range.
--- 17 CURATED, CALIBRATED INSTRUMENTS ---
No more flat, dry synthesizer tones. Tetratonics 2.0 features 17 studio-grade, gain-staged instruments divided across two independent layers:
- 8 CHORD TIMBRES: Rhodes (vintage warmth), Strings (orchestral swell), Synth Pad (ethereal stereo), Vibraphone (metallic bell), Guitar (acoustic pluck), Grand Piano (acoustic benchmark), Perc Organ (classic organ click), and Warm Pad (analog sweep).
- 9 MELODIC TIMBRES: Celesta (crystalline attack), Marimba (wooden resonance), Flute (woodwind breeze), Music Box (delicate chime), E. Piano (percussive bite), Harp (sweeping classical pluck), Clavinet (funk-infused bite), Vocal Lead (wordless swell), and Square Lead (digital retro).
- PRO LOUDNESS PARITY: Every instrument is individually calibrated across three axes (velocity, sampler gain, and output dynamic ceiling). You can switch from a punchy Clavinet to a breathy Flute with zero perceived volume jumps.
--- JAZZ VOICINGS & SHIELDED ENHARMONICS ---
Our Harmonic Intelligence engine actively listens to your choices, dynamically restructuring the accompaniment to support your scale:
- 6 PROFESSIONAL VOICINGS: Stack them closely in Root Position, spread them using Open Position I (Drop 2) and Open Position II (Drop 3), frame them with Root + 7th (Shell), anchor the bass with Root Only, or play our bespoke "Tetratonic" voicing, which seamlessly fuses the chord's core skeleton with your scale notes voiced as a cohesive upper structure.
- THE THEORY DONE FOR YOU: Drop any four-note scale over any chord and watch our engine resolve enharmonic ambiguities (knowing b5 vs #11, b13 vs #5). The scale builder respects key signature gravity (flat roots use flats; sharp roots use sharps) to present flawlessly spelled chord symbols like Cmaj7(9/#11) and G7(alt).
--- THE INTERACTIVE HARMONIC DIAMOND ---
Our 12-tone chromatic visualizer is now a fully interactive instrument. Notes are color-coded by chord function: Core Tones (blue), Guide Tones (green), Extensions (amber), and Altered Tensions (crimson). Tap any note on the outer ring for an instant, haptic-synced audio preview, or tap the center to trigger the full, combined performance.
--- STAGE-READY PRO-AUDIO RESILIENCE ---
Built for the gigging musician:
- ADAPTIVE INTERFACE: Seamlessly rotates between portrait pocket reference and landscape practice layout.
- LIQUID GLASS DARK MODE: Sleek, high-contrast aesthetic designed for lit stages.
- AUDIO RESILIENCE: Gracefully survives phone calls, backgrounding, notification alerts, and hardware changes (AirPods unplugs, Bluetooth device switches) without clicks or dropouts.
- STRICTLY OFFLINE: Zero ads, zero subscriptions, zero tracking.
