Karen Tanaka: 'From the composition of Crystalline for solopiano in 1988, I have desired to project the image of crystals in sounds and space. Hommage en cristal (1991), Metallic Crystal (1994-95) and Crystalline II (1995-96) are linked to this earlier piece, in whicha glassy, solid, yet transparent sound suggests cold, crystal sound sculptures. This idea has been extended and developed in Crystalline III, but it has become more joyful and more rapidly fluttering in space.
