Source sentences:
text: Although an acoustic piano has strings, it is usually classified as a percussion instrument rather than as a stringed instrument, because the strings are struck rather than plucked (as with a harpsichord or spinet); in the Hornbostel–Sachs system of instrument classification, pianos are considered chordophones.
text: The string may be struck, plucked, rubbed (bowed), or, occasionally, blown (by the wind); in each case the effect is to displace the string from its normal position of rest and to cause it to vibrate in complex patterns.
text: The tone of an instrument is also markedly affected by the place where the string is struck.
