Test yourself: Can you tell the difference between music and noise? - Hanako Sawada

In 1960, American composer John Cage went on national television

to share his latest work.

But rather than employing traditional instruments,

Cage appeared surrounded by household clutter,

including a bathtub, ice cubes, a toy fish, a pressure cooker,

a rubber duck, and several radios.

Armed with these tools and a stopwatch, he performed “Water Walk,”

setting off a series of sounds with a serious expression

and incredible precision.

Some viewers found the performance hysterical,

while others thought it was completely absurd.

But most people watching likely shared the same question:

is this even music?

This question is harder to answer than you might think.

What we determine as music often depends on our expectations.

For example, imagine you’re in a jazz club listening

to the rhythmic honking of horns.

Most people would agree that this is music.

But if you were on the highway hearing the same thing, many would call it noise.

After all, car horns aren’t instruments

and these drivers aren’t musicians... right?

Expectations like these influence how we categorize everything we hear.

We typically think something sounds more musical

if it uses a recognizable structure or popular sounds

arranged in well-known patterns.

And even within the realm of music,

we expect certain genres to use specific instruments and harmonies.

These expectations are based on existing musical traditions,

but those traditions aren't set in stone.

They vary across different cultures and time periods.

And in the early 20th century,

when many artists were pushing the boundaries of their fields,

John Cage wanted to discover what new kinds of music might exist

beyond those constraints.

He began pioneering new instruments that blurred the lines

between art and everyday life,

and used surprising objects to reinvent existing instruments.

He also explored new ways for music to mingle with other art forms.

He and his creative and romantic partner, Merce Cunningham,

held recitals where Cage’s music and Cunningham’s choreography

would be created independently before being performed together.

But whatever his approach,

Cage gleefully dared listeners to question the boundaries between music and noise,

as well as sound and silence.

Perhaps the best example is one of Cage’s most famous compositions—

a solo piano piece consisting of nothing but musical rests

for four minutes and 33 seconds.

This wasn’t intended as a prank, but rather, as a question.

Could the opening and closing of a piano lid be music?

What about the click of a stopwatch?

The rustling, and perhaps even the complaining, of a crowd?

Like the white canvases of his painting peers,

Cage asked the audience to question their expectations about what music was.

And while the piece didn’t evoke the drama of some traditional compositions,

it certainly elicited a strong emotional response.

Cage’s work frequently prioritized these spontaneous, ephemeral experiences

over precise, predictable performances.

He even developed processes that left some compositional decisions up to chance.

One of his favorite such systems was the I Ching,

an ancient Chinese divination text.

Using just a handful of coins,

the I Ching allows readers to produce a pattern of lines

which can be interpreted to answer questions and offer fortunes.

But Cage adapted these patterns into a series of tables

that generated different musical durations, tempos, and dynamics.

Eventually, he even used early computers to help produce these random parameters.

For some pieces, Cage went even further,

offering musicians incomplete compositions notated with broad instructions,

allowing them to compose on the fly with the help of his guidelines.

Some composers rejected Cage's seemingly careless approach.

They believed it was the composer’s job to organize sound and time

for a specific, intentional purpose.

After all, if these strange compositions were music,

then where do we draw the line?

But like a bold explorer, Cage didn't want to be bound by restrictions,

and he certainly didn't want to follow old rules.

He dedicated himself to shattering our expectations,

creating a series of once in a lifetime experiences

that continue encouraging musicians and audiences

to embrace the unexpected.
