Chord Frequency Analyzer
Calculate harmonic frequencies and interval ratios for chord analysis
About this calculator
The Chord Frequency Analyzer calculates the exact frequencies and mathematical ratios between notes in musical chords, providing detailed harmonic analysis for musicians, composers, and audio engineers. This tool helps understand chord structure by breaking down complex harmonies into their fundamental frequency relationships. It's essential for music theory study, sound design, audio mixing, and creating custom tuning systems or analyzing chord progressions from a scientific perspective.
How to use
Enter the root note and chord type (major, minor, seventh, etc.) or input individual note names. The calculator will display each note's frequency in Hz and show the interval ratios between all chord tones. Use this data to analyze harmonic relationships, tune instruments precisely, or understand the mathematical foundation of your chord progressions.
Frequently asked questions
What are interval ratios in chord analysis?
Interval ratios show the mathematical relationship between note frequencies, like 3:2 for a perfect fifth, helping understand harmonic consonance and dissonance.
Can I analyze custom or extended chords?
Yes, you can input any combination of notes to analyze complex chords like thirteenths, altered dominants, or custom voicings with their frequencies.
Why do I need to know chord frequencies?
Knowing frequencies helps with precise tuning, audio mixing, sound synthesis, understanding acoustics, and creating harmonically balanced musical arrangements.
