“My very dear friend Broadwood—
I have never felt a greater pleasure than in your honor’s notification of the arrival of this piano, with which you are honoring me as a present. I shall look upon it as an altar upon which I shall place the most beautiful offerings of my spirit to the divine Apollo. As soon as I receive your excellent instrument, I shall immediately send you the fruits of the first moments of inspiration I gather from it, as a souvenir for you from me, my very dear Broadwood; and I hope that they will be worthy of your instrument. My dear sir, accept my warmest consideration, from your friend and very humble servant.
—Ludwig van Beethoven”
As musical instruments improved through history, new kinds of music became possible. Sometimes, the improved instrument could make novel sounds; other times, it was louder; and other times stronger, allowing for more aggressive play. Like every technology, musical instruments are the fruit of generations worth of compounding technological refinement.
In a shockingly brief period between the late 18th and early 19th centuries, the piano was transformed technologically, and so too was the function of the music it produced.
To understand what happened, consider the form of classical music known as the “piano sonata.” This is a piece written for solo piano, and it is one of the forms that persisted through the transition, at least in name. In 1790, these were written for an early version of the piano that we now think of as the fortepiano. It sounded like a mix of a modern piano and a harpsichord.
Piano sonatas in the early 1790s were thought of primarily as casual entertainment. It wouldn’t be quite right to call them “background music” as we understand that term today—but they were often played in the background. People would talk over these little keyboard works, play cards, eat, drink.
In the middle of the 1790s, however, the piano started to improve at an accelerated rate. It was the early industrial revolution. Throughout the economy, many things were starting to click into place. Technologies that had kind of worked for a while began to really work. Scale began to be realized. Thicker networks of people, money, ideas, and goods were being built. Capital was becoming more productive, and with this serendipity was becoming more common. Few at the time could understand it, but it was the beginning of a wave—one made in the wake of what we today might call the techno-capital machine.
Riding this wave, the piano makers were among a great many manufacturers who learned to build better machines during this period. And with those improvements, more complex uses of those machines became possible.
Just as this industrial transformation was gaining momentum in the mid-1790s, a well-regarded keyboard player named Ludwig van Beethoven was starting his career in earnest. He, like everyone else, was riding the wave—though he, like everyone else, did not wholly understand it.
Beethoven was an emerging superstar, and he lived in Vienna, the musical capital of the world. It was a hub not just of musicians but also of musical instruments and the people who manufactured them. Some of the finest piano makers of the day—Walter, Graf, and Schanz—were in or around Vienna, and they were in fierce competition with one another. Playing at the city’s posh concert spaces, Beethoven had the opportunity to sample a huge range of emerging pianistic innovations. As his career blossomed, he acquired some of Europe’s finest pianos—including even stronger models from British manufacturers like Broadwood and Sons.
Iron reinforcement enabled piano frames with higher tolerances for louder and longer play. The strings became more robust. More responsive pedals meant a more direct relationship between the player and his tool. Innovations in casting, primitive machine tools, and mechanized woodworking yielded more precise parts. With these parts one could build superior hammer and escapement systems, which in turn led to faster-responding keys. And more of them, too—with higher and lower octaves now available. It is not just that the sound these pianos made was new: These instruments had an enhanced, more responsive user interface.
You could hit these instruments harder. You could play them softer, too. Beethoven’s iconic use of sforzando—rapid swings from soft to loud tones—would have been unplayable on the older pianos. So too would his complex and often rapid solos. In so many ways, then, Beethoven’s characteristic style and sound on the keyboard was technologically impossible for his predecessors to achieve.
