This page lists the 432 Hz music published on this channel and explains what “432 Hz” means in each case, including one distinction most playlists skip: a 432 Hz tone is not the same thing as music tuned to A = 432 Hz.
Hear 432 Hz first. Play 432 Hz in the Frequency Lab (free, no sign-up). The Lab also has a blind A/B test of 432 Hz against 440 Hz.
Two meanings of “432 Hz”
- A = 432 Hz tuning: ordinary music in which the note A is tuned to 432 Hz instead of the standard 440 Hz. Every note shifts down by about 32 cents. The melody is unchanged; only the overall pitch moves.
- A 432 Hz tone: a sustained tone at 432 Hz used as a drone or base, often with other layers on top.
The tracks below are the second kind. We measured two of their masters: in both the 20-minute focus track and the 8-hour fireflies track, the strongest component is exactly 432.00 Hz. They are built around a 432 Hz tone, not retuned melodies.
432 Hz in numbers
| Item | 432 Hz |
|---|---|
| Nearest piano note (A = 440 Hz) | 32 cents below A4 (440.00 Hz) |
| One cycle | 2.315 ms |
| Wavelength in air (20 °C) | 0.794 m |
| Distance from 440 Hz | 31.8 cents lower (a third of a semitone) |
Whether 432 Hz tuning “sounds better” than 440 Hz is a common question. The maker took the Frequency Lab’s blind test and scored 6 out of 10, which is within the range of guessing (the blind test note). The tuning debate itself is covered in 432 Hz vs 440 Hz.
Our 432 Hz tracks
As of October 2026 the channel has 36 published videos that use 432 Hz (13 long-form). The long-form ones, longest first:
The 6-hour original of the triple stack is not listed: its master was clipped, and it has been replaced by the remastered 8-hour version above.
How these tracks are made
- Every sound is synthesised in-house; no field recordings or sample libraries.
- Loudness is measured after export: −14 LUFS for most tracks, −16.5 LUFS for 8-hour sleep versions.
- Low tones like 432 Hz carry over phone speakers reasonably well, but the deeper layers under them do not. Headphones or a speaker with real bass give the full sound.
Frequently asked questions
Is 432 Hz a Solfeggio frequency?
No. It belongs to the tuning discussion (A = 432 vs 440 Hz), a separate idea from the nine Solfeggio numbers.
Can I hear the difference between 432 and 440 Hz?
Side by side, many people can tell which is lower. Whether one is “better” is a matter of taste; try the blind test in the Lab.
Is there research on 432 Hz?
There are a few small studies comparing 432 Hz and 440 Hz music; results are limited and not conclusive. This page makes no health claims.
