The sound, explained

The Meditation zone doesn't improvise. Every sound rests on simple choices and, where possible, on peer-reviewed work. Here's how it's built and, honestly, what is established and what isn't.

The principle

A deeply consonant pad

The background is a sustained low chord stacked in fifths and octaves (the most stable intervals there are). Nothing 'moves', nothing resolves: the ear settles and expects nothing.

Pentatonic chimes

The ringing notes are drawn at random from a 5-note scale, with no semitone or tritone: whatever the sequence, it always stays soft and in tune. Essential, since the triggering is random.

Tuned to A = 432 Hz

The whole system is shifted down by about 32 cents so the reference A lands on 432 Hz, a tuning often described as gentler. The ratios between notes are unchanged; only absolute pitch slides.

The four intentions

Each intention changes the pitch of the background sound. The lower it is, the more you feel it in the body; the higher it is, the more it opens and lifts.

SootheChord · C–G–CFundamental · 128.4 Hzneutral mid-range → serenity, a starting point
GroundChord · G–D–GFundamental · 96.2 Hzlow, felt in the body → rootedness
OpenChord · D–A–DFundamental · 144.2 Hzhigher, luminous → opening, momentum
RecenterChord · F–C–FFundamental · 171.4 Hza soft colour → brings you back to centre

Why 432 Hz?

It's a tuning choice, not a cure. A few small randomised studies suggest modest effects (slightly lower heart rate, more focus) compared with the standard 440 Hz, but on small samples. We present it as an aesthetic, felt reference, never as a proven therapeutic virtue.

What research shows

We clearly separate what is solidly established from what is emerging, and from folklore.

Solidly established

  • Breathing slowly, around 6 cycles per minute, brings the baroreflex into resonance and raises heart-rate variability. That's exactly what the 'Breath' variable drives.
  • Slow music (60–80 BPM) supports calm (lower heart rate, parasympathetic activity).
  • Nature sounds (water and birdsong) speed up stress recovery. Hence the Water and Earth textures.
  • Perceived consonance comes from harmonicity, encoded as early as the brainstem: that's what makes our pads and scales pleasant.

Emerging (modest effects)

  • 432 Hz vs 440 Hz tuning: real but small effects, on small samples.
  • Binaural beats (on headphones) may reduce anxiety; evidence quality varies.

Not to be believed

  • The 'Solfeggio frequencies' (528 Hz 'that repairs DNA', etc.): numbers invented by numerology in the 1970s, with no evidence. You can use those pitches as notes, never as a healing claim.

Our line

The Meditation zone is a space for rest, informed by research, but not care. We claim to 'heal', 'cure' or 'rebalance' nothing. It does not replace support from a health professional.
