We don't usually, for one moment, consider the piano to be a wind instrument; usually it needs a player to sit and 'hit' it with whatever degree of artistry, and in the appropriate style. Yet sometimes a piano will, in a tenable manner of speaking, be played by means of wind and without a human anywhere near it: how come?
The wind, or a draft, may be blowing through the strings as with an 'aeolian harp'
The strings of the piano may be excited into vibration by other music nearby, such as a passing band
The player-piano ('reproducing') mechanism is powered pneumatically, with holes in the paper roll 'recognised' by an intake of air pressure, and the hammers then activated by a system of windblown bellows
The piano strings vibrate of their own accord when there is a shockwave in the air
