{{main|Piano extended technique}}
* [[prepared piano]], i.e., introducing foreign objects into the workings of the piano to change the sound quality
* [[string piano]], i.e., striking, plucking, or bowing the strings directly, or any other direct manipulation of the strings
* resonance effects (whistling, singing or talking into the piano)
* silently depressing one or more keys, allowing the corresponding strings to vibrate freely, allowing sympathetic [[harmonics]] to sound
* touching the strings at node points to create [[flageolet tone|harmonics]]
* percussive use of different parts of the piano, such as the outer rim
** slamming piano lid or keyboard cover
* microtones
* use of the palms, fists, or external devices to create [[tone clusters]]
* use of other materials to strike the keys
* pedal noises
