A Brief History of the Piano
To understand why pianos have 88 keys, we need to take a step back and look at the instrument’s origins. The piano, as we know it today, is a descendant of the harpsichord, a stringed instrument popular in the Baroque period. In the early 18th century, instrument makers began experimenting with new designs, seeking to create an instrument that could produce a wider range of tonal colors and dynamics.
The Emergence of the Piano
In 1709, Bartolomeo Cristofori, an Italian instrument maker, invented the first piano, which he called “pianoforte.” This innovative instrument used a mechanism called the “action” to strike strings with hammers, producing a softer, more expressive sound than the harpsichord. The early piano had a range of around four octaves, with a narrower keyboard and fewer keys than modern pianos.
The Evolution of the Piano Keyboard
Over the centuries, the piano underwent significant changes, with instrument makers continually expanding its range and improving its design. The number of keys on the piano keyboard increased gradually, driven by the needs of composers and performers.
The Expansion of the Range
In the late 18th century, pianos typically had a range of around five octaves, with 60-70 keys. However, as composers began to write music that required a wider range, instrument makers responded by adding more keys. By the mid-19th century, pianos commonly had a range of six octaves, with 80-85 keys.
The Standardization of the 88-Key Piano
So, why did the piano eventually settle on 88 keys? The answer lies in the late 19th century, when instrument makers began to standardize the piano’s design. The Steinway & Sons company, in particular, played a significant role in establishing the 88-key piano as the norm.
In the 1870s, Steinway & Sons introduced the Model D, a concert grand piano with a range of eight octaves (A0 to C8). This instrument became the gold standard for pianos, and its 88-key configuration was soon adopted by other manufacturers.
The Benefits of the 88-Key Piano
So, what are the advantages of having 88 keys on a piano? Here are a few key benefits:

What is the origin of the 88-key piano, and how did it become the standard?
The origin of the 88-key piano dates back to the late 19th century when piano manufacturers began to standardize the instrument’s range. The first pianos, invented by Bartolomeo Cristofori in the early 18th century, had a much narrower range, typically spanning four octaves. Over time, as music composition evolved and pianists demanded more expressive range, manufacturers expanded the keyboard to accommodate the growing needs of musicians.
The 88-key piano became the standard in the late 19th century, with Steinway & Sons, a renowned piano manufacturer, playing a significant role in popularizing this range. The company’s Model D concert grand piano, introduced in the 1880s, featured the now-standard 88 keys, which provided a suitable balance between playability and expressive range. This design eventually became the industry standard, adopted by other manufacturers and widely accepted by pianists and composers.
