From 528Hz,
a piece of music opens.

When exploring sound,
sometimes a single number
opens up an unexpected world.

444Hz is one of those numbers for me.

It all began with 528Hz.

Known as one of the Solfeggio frequencies,
it is a frequency you often see
in the world of crystal bowls as well.

As I kept looking at the number 528Hz itself,
I gradually became curious about what lay beyond it.

What would happen
if I placed the sound of 528Hz inside actual “music”?

What if I played it with a piano?

What if I treated it as C?

What if I built chords from there?

From a single frequency,
a search for relationships between sounds began.

Where does 528Hz sit?

Calculating in the widely used
twelve-tone equal temperament at A=440Hz,

C5 (do) is about 523.25Hz.

That is about 4.75Hz away from 528Hz.

Even among sounds near the same “do,”
when you actually play them,
this difference appears as resonance.

So then,

if 528Hz is placed as C,
where does the reference for the whole of the music fall?

Working backward,
the number A=444Hz appears.

A=444Hz

Set A to 444Hz
and calculate in twelve-tone equal temperament,

and C5 is about 528.01Hz.

Almost exactly 528Hz.

Here, the single frequency of 528Hz
becomes the note C,
and begins to have a place within the scale.

I find this moment
truly fascinating.

What was a single point
begins to form relationships with other sounds.

A single frequency
expands into music.

Seeing relationships of resonance through numbers.

When I look at frequencies,
I am not just following rows of numbers.

I want to know what can be heard
when those numbers actually become sound.

If 528Hz is C,
where is E?

And G?

In equal temperament?

In pure intonation?

If I search for that sound among crystal bowls,
what overtones does it have?

If I actually layer three sounds,
what resonance is born in the space?

When one answer is found,
the next question arises.

Calculate.
Search.
Measure.
Play.
Listen.

And then calculate again.

My research on sound
will probably always be this cycle.

From 528Hz, and beyond.

Many meanings and interpretations
are attached to the number 528Hz.

From there, I want to take one more step
into the world that can actually be heard.

Playing 528Hz.

Letting it meet other sounds.

Layering it with a piano.

Building chords with crystal bowls.

Receiving that resonance with the body.

Then,
from the single number “528Hz,”
music begins to be born.

For me, 444Hz is
a fascinating coordinate
I found along the way.

Sound holds relationships we do not yet know.

432Hz.
440Hz.
444Hz.

Rather than making any one of them the answer,
I want to hear how the world of sound changes
when the reference changes.

Move one sound,
and its relationships with other sounds move too.

When relationships change,
resonance changes too.

And so,
our senses that receive that resonance change as well.

I thought I was chasing numbers,
yet before I knew it,
I was looking at the “in-between” of sounds.

That, I think,
is what I love.

From 528Hz to 444Hz.

And on to the resonance beyond,
one I have never heard before.

The research continues.
