The piano is today one of the most recognizable and versatile instruments in the world, used in classical music, jazz, pop genres and even film orchestrations.
But its path to this popularity began with the attempt of ancient thinkers to understand the nature of sound. From the monochord of Pythagoras, through medieval stringed instruments, to the revolutionary invention of the Italian Bartolomeo Cristofori, the piano has constantly evolved, driven by the pursuit of better sound, greater expression and more perfect mechanics.
This history reveals not just the evolution of an instrument, but over a millennium of human curiosity, ingenuity and musical passion.
The path to the emergence of the piano began not with a keyboard instrument, but with a scientific device called the monochord, created by the ancient Greek philosopher and mathematician Pythagoras. He invented the monochord as a scientific instrument for measuring musical intervals (the distances between two tones). Pythagoras discovered that different string lengths produced different pitches.
When he reduced the length of the string by half, the tone sounded an octave higher. Other lengths or ratios produced pleasant-sounding tones.
Pythagoras’ discoveries laid the foundation for Western music and demonstrated the natural, mathematical relationship between different tones.
Although the monochord itself was not a musical predecessor to the piano, it laid the foundation for understanding acoustics and the relationship between string length and pitch.
Pythagoras discovered that different ratios of string length produced different intervals, revealing the mathematical principle upon which all stringed instruments were later built. It was this knowledge, not the instrument itself, that laid the theoretical foundation for future keyboard instruments such as the clavichord, harpsichord, and ultimately the piano.
Another ancient instrument, the organ, inspired the use of keys.
The history of the organ begins in the 3rd century BC with the invention of the hydraulics by the ancient Greek engineer Ctesibius in Alexandria. This is a water-powered instrument, considered the first keyboard mechanism in the world.
The Romans improved the design and turned the instrument into a symbol of power and technological progress, used in public celebrations and ceremonies.
After the decline of Rome, the instrument almost disappeared, but around the 10th century it reappeared in Europe, this time as part of the Christian liturgy. The first church organs were huge and difficult to control, but gradually their size was reduced, a keyboard and a more precise mechanism were developed.
During the Middle Ages, the organ became an indispensable element of church music, and by the Renaissance it already had a richer sound and a more perfect construction, which laid the foundations for its future flourishing during the Baroque period.
The organ eventually became the prototype for the clavichord in the late 14th century.
Before the addition of keys to the clavichord, there was the dulcimer, a favorite instrument of musicians in Western and Eastern Europe during the Middle Ages.
The idea of strings struck by hammers was the humble precursor to the modern piano. But it would be several more centuries before anything resembling a modern piano would emerge from the workshop of Bartolomeo Cristofori.
Bartolomeo Cristofori is the man generally credited with inventing the piano. He called his invention the gravicembalo col piano e forte (“harpsichord that plays softly and loudly”) because the instrument could vary the volume of the sound according to how hard the keys were pressed, something the harpsichord could not do.
Cristofori’s invention solved the problems of simple mechanisms, as well as almost all the other difficulties that piano makers faced until the 19th century.
Cristofori’s innovative design and mechanics only became public knowledge after a visit by the Italian journalist Scipio Maffei. Two years later, an article with illustrations of his construction appeared.
The German organ builder Johann Gottfried Silbermann copied the design and adapted it.
Other craftsmen also used the model and created their own versions. This gave rise to the English and Viennese schools of piano making.
Cristofori achieved this by replacing the plucking mechanism with hammers that could strike with either a strong or weak force.
By 1726, Cristofori had perfected his instrument and introduced all the basic elements of modern piano mechanics.
In Italy, his design was almost ignored, but it soon became known and accepted in Germany.
Around 1870, the modern piano was born. Since then, its production and design have hardly changed significantly.
The emergence of the modern piano also strengthened the middle class. In 1909, about 365,000 pianos were sold, compared to only a few thousand in 1850. During the Industrial Revolution, factories and cast iron played a key role in making music accessible to everyone.
Grand pianos usually have two (or three) pedals. Most often, the left pedal shifts the keyboard to the right, and the hammers strike only two of the three strings – this is the una corda pedal, similar to that of a harpsichord, where only one of the strings is struck. The disadvantage is the change in timbre. The right pedal is the sustain pedal, which raises the dampers and allows the strings to vibrate freely. Grand pianos also have a third pedal, located in the middle. If used at the right moment, the pianist can hold certain notes while playing new ones on them without losing the support of the first ones.
Since 1885, the piano has been standardized, and innovations have become increasingly rare. Cristofori’s mechanism has been improved over the next two centuries, but the foundation remains unchanged.
The piano, as we know it today, is the result of centuries of research, study, and refinement. From the scientific instrument of Pythagoras, through the delicate clavichord and the rich-sounding harpsichord, to the first piano mechanism of – each stage adds a new layer to the musical history of mankind.
After its standardization in the 19th century, the piano has become a symbol of cultural prosperity, artistic mastery, and family tradition. While innovations are rare today, the piano remains timeless – an instrument that continues to inspire composers, performers and listeners around the world with its power, beauty and vast expressive possibilities.
