Pianos And Organs

The piano (or pianoforte to give it its proper name) is a musical instrument with a keyboard. A normal piano has 88 keys. Pianos use the keys to move hammers that hit strings inside, making a sound. Pianos come in two basic shapes: grand pianos and upright pianos. The piano has been an extremely popular instrument in Westernclassical music since the late 18th century. A person who plays the piano is called a pianist.

In music, the organ (from Greek ὄργανον organon, "organ, instrument, tool")[1]is a keyboard instrument of one or more divisions, each played with its own keyboard, played either with the hands or with the feet. The organ is a relatively old musical instrument,[2] dating from the time of Ctesibius of Alexandria, who is credited with inventing the water organ. It was played throughout the Greek and Roman world, particularly during races and games.[3] During the early medieval period it spread from the Byzantine Empire, where it continued to be used in secular and imperial court music, to Western Europe, where it gradually assumed a prominent place in the liturgy of theCatholic Church.[3] Subsequently it re-emerged as a secular and recitalinstrument.
