Tetratonics: The 4th Dimension

Four Notes. Infinite Color.

$0.99

Step into the 4th dimension of modern jazz harmony. One triad. One added note. Infinite color. Tetratonics reveals the secret behind modern jazz voicings: take a major or minor triad you already know, add one carefully chosen color tone, and superimpose the resulting 4-note tetratonic structure over any chord. The result is immediate - beautifully sophisticated harmony, effortlessly within reach. Built as the ultimate harmonic laboratory for improvisers, composers, and arrangers, every feature bridges the gap between abstract theory and concrete sound. --- THE CORE SYSTEM: 10 CURATED STRUCTURES Tetratonics curates the 10 highest-value "Triad + 1" combinations used in contemporary jazz: - 6 Major-Based Structures: (b2), (2), (#2), (4), (#4), (b6) - 4 Minor-Based Structures: -(b2), -(2), -(4), -(#4) This masterable system is meticulously optimized for harmonic beauty and functionality. Every combination sounds incredible. --- THE HARMONIC VISUALIZER Our stunning visualizer brings your harmony to life by mapping out exactly how your chosen tetratonic structure relates to your underlying chord on a 12-tone chromatic ring. - See the tetratonic pitches form a unique geometric shape that reflects intervallic relationships in detail. - Notes are color-coded by harmonic function: Core Tones (blue), Sevenths (green), Natural Extensions (amber), and Altered Tensions (crimson). - Tap the interactive ring to smoothly pivot your starting point. --- FLAWLESS ENHARMONIC CALCULATION Our proprietary engine handles complex enharmonic calculations with absolute precision. The intelligent scale builder respects the enharmonic gravity of your chord - over flat roots, you see flats; over sharp roots, you see sharps. Every single pitch is spelled correctly. --- INSTANT CHORD TRANSLATION Drop a Triad + 1 structure over any Major, Minor, or Dominant chord and our analytical engine decodes the result. The app distinguishes between complex contextual choices (knowing when an interval functions as a b5 versus a #11) and outputs the perfect, standard-compliant jazz chord symbol. Instantly see how a simple structure creates a lush Cmaj7(9/#11/13), a detailed Fmin7(9/b13), or a powerful G7(#9/13). --- SMART CONTEXT AWARENESS Change your base chord root or quality, and Tetratonics instantly recalculates valid starting points, displaying only combinations that sound coherent. It actively keeps you in a state of creative flow. --- THE CONTROL ISLAND A tactile interface designed for quick adjustments. Rapidly switch between the 10 master archetypes and see your tetratonic formula and the resulting musical pitches side-by-side. --- PERSONAL FAVORITES LIBRARY When you stumble upon a killer voicing or altered dominant color that feels electric, tap the star icon to save it for your next practice or writing session. --- DESIGNED FOR MUSICIANS, BY MUSICIANS Built to feel like a high-end piece of gear: - Adaptive Layout: Shifts perfectly between portrait pocket reference and spacious landscape mode. - Premium Dark Mode: A "liquid glass" aesthetic that preserves your vision on lit stages. - Haptic Touch: Tuned tactile feedback connects physical touch to harmonic explorations. - Strictly Offline: Zero ads, zero subscriptions, zero data collection. Runs entirely locally on your device. --- If you know your major and minor triads, you are already ready. Discover a lifetime of modern harmonic color with Tetratonics today.
