Pianos and organs belong to the keyboard family of musical instruments which also includes pipe organs, hurdy gurdy, clavichord, harpsichord, accordions and many more. The organ is the oldest keyboard instrument. Pianos appeared in the 18th century and quickly became popular, because they enable the player to vary the volume of sound by varying the force with which the keys are struck. Another name for piano is "piano-forte", which means "soft-loud" in Italian.
