Piano - Visual Summary map


Widely used in classical and jazz music for solo performances, ensemble use, chamber music and accompaniment, the piano is also very popular as an aid to composing and rehearsal.
Although not portable and often expensive, the piano's versatility and ubiquity have made it one of the world's most familiar musical instruments.
Pressing a key on the piano's keyboard causes a felt-covered hammer to strike steel strings.
The hammers rebound, allowing the strings to continue vibrating at their resonant frequency.
These vibrations are transmitted through a bridge to a sounding board that more efficiently couples the acoustic energy to the air.
The invention of the modern piano is credited to Bartolomeo Cristofori (1655–1731) of Padua, Italy, who was employed by Ferdinando de' Medici, Grand Prince of Tuscany, as the Keeper of the Instruments.
