Nightingale floor

This video illustrates the sound of the nightingale floor, uguisubari 鴬張り, by recordings from two different sites in Kyoto: Nijo-jo caste and Tōfuku-ji temple. The floor’s characteristic melodic squeek is the result of a special construction technique involving nails and clamps that rub against each other. The singing floor boards have been likened to that of the japanese bush warbler, uguisi, the sound of which is included as a reference. Legend has it that the nightingale floor was used in the feudal era as a way to warn inhabitants from approaching enemies.
