Piano and 'La La Land's' City of Stars

"City of Stars" from La La Land rides on a deceptively simple piano melody, yet the instrument behind it carries centuries of fascinating history. Bartolomeo Cristofori invented the piano around 1700, replacing the harpsichord's plucking mechanism with a hammer action that finally let musicians control soft and loud expression. Today, 21 million Americans play piano, and science proves it literally rewires your brain. There's far more to this remarkable instrument than you'd expect.

Key Takeaways

• Bartolomeo Cristofori invented the piano around 1700, naming it "clavicembalo col piano e forte," meaning it could play both soft and loud.
• A standard piano contains roughly 220–230 strings, over 7,000 parts, and spans more than seven octaves across 88 keys.
• "City of Stars" from La La Land features piano-driven melody, reflecting the instrument's versatility across jazz, classical, and cinematic genres.
• Concert grand pianos bear up to 30 tonnes of total string tension, enabling the powerful, expressive sound central to film scores.
• Piano training measurably boosts IQ by nearly 3 points after just 9 months, highlighting its cognitive and emotional benefits.

Who Actually Invented the Piano and Why

The piano traces its origins to Bartolomeo Cristofori, a skilled harpsichord maker born in Padua, Italy, in 1655. In 1688, the Florentine court appointed him to care for Grand Prince Ferdinando de' Medici's instrument collection, where he'd channel his expertise into something revolutionary.

His motivation was simple: the harpsichord couldn't respond to a musician's touch. It plucked strings mechanically, offering zero control over volume. Cristofori's innovation replaced that plucking mechanism with a hammer action, releasing dynamic expression that musicians had never experienced before. You could now play softly or powerfully based purely on your touch. He even gave his creation a name that reflected this breakthrough: clavicembalo col piano e forte, meaning "harpsichord that can play soft and loud," which was eventually shortened to simply "piano."

Among his most critical technical contributions was the escapement mechanism, which allowed the hammer to fall away instantly after striking the string, preventing it from dampening the note. His new instrument also used thicker strings at higher tensions than the harpsichord, contributing to its distinctly fuller sound. Much like Michelangelo, who initially resisted his famous commission before producing a monumental artistic achievement, Cristofori's reluctant path of experimentation ultimately transformed the cultural landscape of his era.

What's Actually Inside a Piano: Strings, Tension, and Materials

Crack open a piano and you'll find a surprisingly complex web of components working in precise harmony.

You're looking at roughly 220–230 steel strings, each strung by hand across bass, tenor, and treble ranges. String metallurgy plays a central role here — treble strings use high-carbon steel for brightness and projection, while bass strings wrap a steel core in copper wire to add mass and produce warmer, lower tones.

Each string carries tension equivalent to about 75kg, and tension distribution across all strings totals 16–20 tonnes in a standard piano, reaching 30 in a concert grand. A cast-iron frame absorbs that force, something early wooden frames couldn't handle.

Higher tension directly improves volume, power, and pitch stability through temperature changes. Higher tension also produces more complex string vibrations, resulting in a brighter and fuller timbre across the instrument's full range.

Strings are available in around 20 different gauges, each diameter carefully selected to suit the specific tonal and tension requirements of its position across the keyboard's full range.

Why the Piano Has the Widest Tonal Range of Any Instrument

Spanning more than seven octaves, the piano stretches from A0 at 27.5 Hz all the way up to C8 at 4186 Hz — a range no other conventional instrument comes close to matching. You're hearing a spread that fits almost entirely within human hearing's 20 Hz to 20,000 Hz window, with overtones from C8 reaching as high as 16,744 Hz.

String density shifts dramatically across the keyboard, with thicker, heavier strings handling the bass register and thinner strings managing the upper range. That variation directly supports sound projection across every register without sacrificing tonal clarity.

Instruments like the piccolo cover fewer than three octaves, and the double bass stays locked to its own narrow band. The piano's 88 keys simply outpace them all. The 4th overtone of C8 lands at roughly 20,930 Hz, just beyond the upper boundary of human hearing and therefore lost to perception entirely.

Beyond raw span, the piano's keyboard layout makes it a natural reference point for visualizing where any instrument sits on the pitch spectrum, since size and location together define what a range truly means in practice.

What Makes the Piano the "King of Instruments"?

Few instruments earn a title like "King of Instruments," but the piano backs it up with sheer complexity alone — 88 keys, 230 strings, and over 7,000 individual parts packed into a frame weighing anywhere from 300 to over 1,000 pounds.

Bartolomeo Cristofori invented it around 1700 specifically to add dynamic control over the harpsichord's flat, plucked sound. That innovation changed everything. You can play softly or powerfully, alone or alongside any orchestral or band instrument.

Its polyphonic versatility lets your two hands independently handle melody, harmony, and bass simultaneously — something few instruments can match. Classical, jazz, rock, hip-hop — the piano moves through every genre without losing relevance. Its tonal range spans the full orchestra, reaching lows comparable to the double bassoon and highs comparable to the piccolo.

That combination of power, range, and adaptability is exactly what makes the title stick. Before Cristofori became the instrument's inventor, he served the Grand Prince of Tuscany in the official role of Keeper of the Instruments, a position some theorize directly inspired the word "piano" itself.

The Record-Breaking Pianos You Won't Believe Exist

Some pianos don't just make music — they make history, and their price tags prove it.

The Casablanca movie piano, a miniature upright used in the 1942 film, fetched $3.4 million at auction — the highest ever recorded.

Celebrity auctions have produced equally stunning results: George Michael paid $2.1 million for John Lennon's Steinway upright, the very instrument that gave birth to "Imagine."

The crystal Heintzman, debuted at the 2008 Beijing Olympics before nearly one billion viewers, sold for $3.22 million.

If you prefer owning than bidding, the Steinway "Pictures at an Exhibition," painted by Paul Wyse, is available for $2.5 million.

Each piece reflects precision craftsmanship and cultural significance that transforms these instruments from musical tools into priceless artifacts. The Steinway Fibonacci, for instance, required over 6,000 hours of meticulous work and took four years to complete.

The C. Bechstein Sphinx, a Napoleon Bonaparte Empire-style grand adorned with Greek, Egyptian, and Roman motifs, demanded 32 months of construction and over 1,800 hours of artisanal work to complete its $1.2 million masterpiece. Much like Hokusai's The Great Wave off Kanagawa, which used Prussian Blue pigment — a synthetic and newly affordable material — to achieve its iconic vibrancy, exceptional artistry often hinges on the innovative use of materials.

How the Piano Became America's Most Popular Instrument

While record-breaking pianos command millions at auction, the instrument's true power lies in how deeply it rooted itself in everyday American life. Before 1850, Americans imported nearly every piano they owned. That changed fast. By 1890, the U.S. supplied half the world's pianos, selling up to 364,000 annually by 1928.

Mass production made ownership realistic for middle-class families. Home salons became cultural gathering spaces, where pianos served as the centerpiece of entertainment before recorded music existed. Classroom impact shaped generations, establishing piano as the foundation of music education nationwide.

Today, 21 million Americans play piano. It remains the top instrument requested by young musicians and ties with guitar among adults searching to learn. That's not coincidence — it's the result of centuries of deliberate cultural embedding. Unlike guitars or violins, pianos can go decades without needing parts replaced, making them a low-maintenance investment that families were more willing to commit to across generations. Major American manufacturers like Chickering, Steinway, and Baldwin built the industry from the ground up, with manufacturing hubs in New York, Boston, and Chicago driving production that would eventually supply markets across the globe.

How Learning Piano Rewires the Brain and Boosts Academic Performance

When you sit down to practice piano, you're doing far more than learning music — you're physically reshaping your brain.

Every session builds neural pathways across motor, visual, and auditory regions, strengthening how both hemispheres communicate. These changes drive real academic gains.

Research shows piano training delivers measurable results:

• IQ increases nearly 3 points after just 9 months of practice
• Spatial and mathematical skills improve, directly boosting classroom performance
• Memory strengthens through memorizing complex note sequences
• Anxiety and depression scores drop following short-term training

Your brain doesn't just adapt — it grows more connected, faster, and resilient. Musicians show structural differences in areas tied to hearing, motor actions, memory, emotion, attention, and learning across multiple brain regions.

A University of Bath study found that just a few weeks of piano lessons significantly improved participants' ability to process audio-visual information simultaneously, with benefits extending beyond music to everyday tasks like watching TV and crossing roads.

Stop practicing, though, and those benefits fade. Consistency isn't optional; it's everything.
