The piano is a musical instrument classified as a string and percussion instrument. It consists of a keyboard with black and white keys that, when pressed, trigger hammers to strike strings within a wooden case. The piano produces sound through the vibration of these strings, which can be varied in volume and tone by adjusting the force with which the keys are struck. It is capable of playing both melody and harmony, making it a versatile instrument in various musical genres, including classical, jazz, pop, and more. The piano is known for its wide range, typically spanning seven octaves plus a minor third, and is often used as a solo instrument, in ensembles, or for accompanying singers and other instruments. Its design and mechanism facilitate expressive playing styles and dynamics, contributing to its popularity and significance in music.
