PURPOSE:To make a beginner possible to obtain fingering condition when the beginner exercises instrument performance according to a navigator or the like, to judge the correctness of the fingering and to navigate the fingering condition, too. CONSTITUTION:A CPU 101 generates magnetic field successively from loop coils of the sum ten fingers of gloves which a performer puts on both hands by successively operating ten pieces of magnetic field generators 108 through a decoder 106, a latch 107 whenever it reads out and specifies the fingering condition for navigation from a ROM 102. The CPU 101 detects whether or not magnetic field detectors 111 provided corresponding to respective keys detect the magnetic field at every magnetic field generation operation from respective finger tips by successively operating six pieces of detection circuits 110. Thus, the CPU 101 obtains the fingering condition of the performer, and by comparing it with the specified fingering condition for navigation, the CPU 101 decides whether or not the fingering of the performer is correct, and controls the navigation operation. |
