PROBLEM TO BE SOLVED: To provide a performance detecting device having a simple structure and requiring no complicated work in the case of being mounted on a keyboard instrument. SOLUTION: Pressure sensors 33 for detecting the pressure of key-pushing and a transmission part 31 for transmitting signals having different frequencies on each finger are installed on positions corresponding to each finger of gloves 3R, 3L mountable on hands. A CPU detects timings of key-pushing and key- releasing and key-pushing strength by information detected by the pressure sensors 33, and detects the position of a finger executing key-pushing according to a reception level, at a reception part, of a radio wave transmitted from the transmission part 31, thereby specifies the pushed key. |
