Free · Designed for iPad
Learn music theory through the lens of mathematics and computer science! Music Theory Matrix offers dynamic lessons which help solidify the foundations for music!
Music Theory Meets Computer Science
Ever wondered why certain combinations of notes sound beautiful while
others clash? This groundbreaking app reveals the mathematical secrets
behind music, making theory accessible through algorithms, data
visualization, and computational thinking.
MATHEMATICAL FOUNDATION
• See the 12th root of 2 (~1.0595) that governs note frequencies
• Interactive frequency calculator: A4 = 440Hz × 2^(semitones/12)
• Visualize how octaves are perfect 2:1 frequency ratios
• Pattern recognition in scale intervals: [2,2,1,2,2,2,1] for major
scales
DATA VISUALIZATION
• Interactive piano with mathematical note mapping
• Visual pattern detection in chord and scale structures
• Circle of Fifths visualization showing key relationships
ALGORITHMIC LEARNING
• Chord construction algorithms: Root + [0,4,7] = Major triad
• Scale generation from interval patterns
• Harmonic series visualization and overtone analysis
• Programming-style logical approach to music theory
INTERACTIVE LABORATORY
• Experiment with mathematical relationships in real-time
• Instrument synthesis allowing you to hear the examples
• Adjustable parameters to see how math affects sound
• Pattern-based learning that clicks for analytical minds
NEW FEATURES & IMPROVEMENTS
• Expanded chord types: 40+ variations including extended, altered, and
power chords
• Interactive chord progressions - tap to play any progression
• Advanced progressions section with jazz, modal, and chromatic examples
• Functional Harmony visualization (Tonic, Subdominant, Dominant)
• Enhanced full-screen piano
COMPUTER SCIENCE CONCEPTS
• Arrays & Indices: Notes as array positions [C=0, C#=1...]
• Signal Processing: How digital audio represents analog waves
• Algorithms: Step-by-step chord and scale construction
PERFECT FOR
• STEM students discovering music's mathematical beauty
• Programmers and engineers learning music theory
• Music students who think in logical patterns
• Anyone who loves understanding "how things work"
WHY THIS APPROACH WORKS
• Eliminates memorization through pattern recognition
• Uses familiar programming concepts (arrays, functions, loops)
• Visual feedback makes abstract concepts concrete
• Mathematical precision removes guesswork
"Finally, music theory that makes sense!" - Perfect for logical thinkers
who've struggled with traditional music education.
Transform your understanding of music through the lens of mathematics and
computer science. No prior music knowledge required - just curiosity
about patterns, numbers, and beautiful sounds.
