What You're Seeing
The visuals are generative educational maps, not direct physical measurements of sound.
A real plate depends on material, size, thickness, excitation point, amplitude and surface.
This project avoids therapeutic or scientific claims and focuses on audible and visual comparison.

432 vs 440 Hz Comparator Guide
What is the 432 vs 440 Hz Comparator?
The 432 vs 440 Hz Comparator is an educational audio tool for comparing two A4 tuning references. It lets you hear the same chord at A4 = 432 Hz and A4 = 440 Hz, review the resulting note frequencies, and study how interval relationships can be represented visually.
How to use the tuning comparator
Choose a root note, select a chord type, press Play, and switch between the two tuning bases. The frequency table shows the measured pitch difference, while the visual panels provide a structured way to compare chord shape, symmetry and movement.
What is A4 = 432 Hz?
A4 = 432 Hz means the A above middle C is tuned to 432 cycles per second. In equal temperament, the rest of the chromatic scale is calculated from that reference, so every note is slightly lower than it would be with A4 = 440 Hz.
What is A4 = 440 Hz?
A4 = 440 Hz is the most common modern concert pitch reference. It is widely used in orchestras, digital instruments, tuners and music production software, which makes it a practical baseline for comparison.
Does 432 Hz sound different from 440 Hz?
Yes. A4 = 432 Hz is lower than A4 = 440 Hz by about 31.8 cents. This produces a subtle but audible pitch shift across the full chord. The difference is musical and measurable; it should not be presented as medical, spiritual or scientifically guaranteed.
Cymatics-inspired visualization disclaimer
The nodal pattern is a cymatics-inspired generative model, not an exact physical simulation. Real cymatic plates depend on material, size, thickness, excitation point, amplitude and surface behavior. Here, interval ratios and tuning references are translated into visual structure for educational comparison.
FAQ
What is 432 vs 440 Hz?
432 Hz and 440 Hz are two A4 tuning references. This tool compares how chords shift when the reference changes.
How do I use this comparator?
Choose a root note and chord type, then play and compare the two tuning references.
Does 432 Hz sound different from 440 Hz?
Yes. A4 = 432 Hz is lower than A4 = 440 Hz by about 31.8 cents. The difference is musical and measurable, not a guaranteed health or emotional effect.
Is the cymatics-inspired pattern a physical simulation?
No. It is a generative nodal model for educational comparison, not a measurement of a real plate or acoustic experiment.
