Abstract:
1. A musical instrument comprising: a performance operator; a hammer that is mechanically driven in response to operation of said performance operator so as to abut against an abutted member; a detector that detects movement of said hammer; a presumption section that, on the basis of outputs of said detector and a given reference value for defining a reference position slightly before a predetermined end position, presumes said hammer will abut against said abutted member when said hammer has reached the reference position; a determination section that determines that said hammer mechanically driven has reached an abutting position where said hammer actually abuts against said abutted member; and a correction section that corrects a presuming condition to be used by said presumption section, in accordance with a presumption result of said presumption section and a determination result of said determination section.
