Abstract
A keyboard musical instrument is provided in which variations in the detection mechanism is corrected so that an appropriate musical sound control can be performed. Detection sections SW, SW, and SWdetect an object at detection positions pSW, pSW, and pSW. On the basis of a detection timing (rT) by the detection section SW, a detected key depression speed (V), and a detection timing (rT) by the detection section SWin a case where the key is depressed in a derivation mode, after a rSTvalue is calculated, a stroke correction value calSTis derived as correction information J and stored in a memory. In the performance mode, the musical sound is controlled on the basis of the detection timing by the detection sections SW, SW, and SWand the stroke correction value calST
