Piano extended techniques are those in which unorthodox or unconventional techniques are used to create the sound. ==Techniques== * prepared piano, i.e. introducing foreign objects into the workings of the piano to change the sound quality * string piano, i.e. hitting or plucking the strings directly or any other direct manipulation of the strings * sound icon, i.e. placing a piano on its side and bowing the strings with horsehair and other materials * whistling, singing or talking into the piano (with depressed sustain pedal) * silently depressing one or more keys, allowing the corresponding strings to vibrate freely, thus creating a kind of reverb effect * percussive use of different parts of the piano, such as the outer rim * flageolet: creating harmonics by touching overtone positions on the string with the finger of one hand and hitting the respective key with the other hand * use of the palms of the hands or the fists—or indeed other body parts—to strike the keys * use of other materials to strike the keys * bowing the strings with bundles of fishing line - introduced by John Cage * palm muting, i.e. placing one hand on the string(s) to mute them while playing the keys with the other hand. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Piano extended technique」の詳細全文を読む スポンサード リンク
