http://pianoeducation.org/pnopnfaq.html retrieved 22 March 2012 The piano is really a "hybrid"--a combination of two types. It's a string instrument because the musical tones originate in the strings; and it's also a percussion instrument, because the strings are set into vibration by being struck with hammers. To be historically correct, it's classified as a "keyed zither" by musicologists.

„Is the Piano a Percussion Instrument?”. Архивирано из оригинала 2012-04-19. г. Приступљено 2012-03-22. retrieved 22 March 2012: How you class the piano depends on which of the following classification schemes you feel is most relevant: (1) By how the sound is produced. By one thing striking another (percussion), by plucking or bowing (strings), or by vibrating a column of air (wind). (2) By construction. If you can’t make the sound without the strings, then call it a stringed instrument. (3) By method of playing. If you use a keyboard, it’s a keyboard instrument; if you hit it with a stick, it’s a percussion instrument. Traditionally, the first classification scheme has held sway. Number 2 is not widely accepted. But Number 3 is gaining ground. For now, most musicologists would agree, the piano is a percussion instrument, and also a keyboard instrument.
