Harmonics are integer multiples of the fundamental frequency.
We map each frequency to the nearest equal-tempered note name for a quick reference.
Start with A3 at 220 Hz.
1st: 220 Hz
2nd: 440 Hz
3rd: 660 Hz
Result: 220 Hz → 440 Hz → 660 Hz
How many harmonics can I show?
Up to 32 are shown here.
What is the fundamental?
It is the base frequency of the tone.
Why use note names?
They make the harmonic pattern easier to read musically.
Can I use decimals?
Yes, the fundamental frequency accepts decimal values.
