What is a piano?
A keyboard built around the power of touch.
A piano is a stringed keyboard instrument. Pressing a key sets a felt-covered hammer in motion; the hammer strikes a string and immediately rebounds so the string can vibrate. How firmly the key is played changes the sound from soft to loud.
That responsive touch is the idea behind the name pianoforte: an instrument capable of both “soft” and “loud.” Digital pianos recreate the playing experience electronically, using sampled or synthesised sound through speakers or headphones.

The evolution of touch
More than 300 years in the making.
Before the piano, harpsichords plucked their strings and clavichords offered expression at a much quieter volume. Cristofori’s hammer action opened a new path: one keyboard could respond to the player’s touch with both power and nuance.
- c. 1700
A new kind of touch
Bartolomeo Cristofori develops a successful hammer-action keyboard instrument in Florence, enabling soft and loud playing through touch.
- c. 1800
The upright takes shape
Vertical strings make the piano more compact. Uprights later become the dominant form for many homes.
- 1821
Faster repetition
Sébastien Érard patents a double-escapement action, helping pianists repeat notes more rapidly.
- 19th century
A larger, stronger voice
Iron framing, overstringing and an expanding compass help the piano gain power, range and tonal depth.
- By the 1890s
88 keys become standard
The familiar A0-to-C8 keyboard settles into the modern 88-key range used by most acoustic pianos.
- 1980s onward
Piano enters the digital age
Digital instruments bring sampled sounds, touch-sensitive keys, headphones and MIDI into homes, studios and classrooms.
Historical claims are based on The Metropolitan Museum of Art’s Cristofori collection and essay, and Encyclopaedia Britannica’s piano and keyboard-instrument histories.
Three familiar forms
Same musical language. Different spaces.
The right instrument depends on where you play, how you practise and the touch and sound you want.
Grand piano
Horizontal strings and a broad soundboard create exceptional control, resonance and projection.
Upright piano
A vertical frame saves floor space while preserving the acoustic relationship between keys, hammers and strings.
Digital piano
Electronic sound, headphones and practical connectivity make focused home practice easier, without acoustic tuning.
