Title A name given to the resource Butterfly piano Subject The topic of the resource Free Music Description An account of the resource Iron, wood, steel, ivory, ebony, nails. Keen to explore the possibilities of Free Music, but lacking instruments that would readily play the ‘noteless’ gliding tones it required, Grainger and Cross modified existing instruments to make approximations of the intended effect. This Butterfly piano has had its lid and front panels removed, and some of the strings have been lengthened using nails as supports. The strings have then been re-tuned to musical pitches much closer to each other than regular piano notes. This instrument was tuned in 1/6 tones, so that playing a scale on it would produce a wave-like gliding tone effect.
