摘要： An electronic musical instrument comprising fret members (24) located at predetermined spacings, a string (16) stretched over the fret members and contactable with any of the fret members when depressed by a player, a fret-position detector (28) for producing supersonic vibrations in the string and receiving the supersonic vibrations reflected from any of the fret members through the string, the supersonic vibrations transmitted from the fret-position detector being reflected from a fret member contacted by the string, wherein the fret member contacted by the string is detected on the basis of a threshold value and or a reference time interval determined in respect of the string responsive to the supersonic vibra­tions transmitted from and reflected to the fret-position detector during a parameter adjusting mode of operation. The instrument may further comoprises a bent-string detector for detecting an amount of lateral displacement of the string on any of the fret members and producing data representative of the detected amount of displacement of the string, wherein the amount of displacement of the string detected during a playing operation is compared with data representative of the amount of displacement detected with the string maintained in a non-bent state for producing bent-string data representa­tive of a corrected amount of displacement of the string.

摘要： A plurality of strings are extended along a surface of a body, and an operation by a player with respect to the strings is detected by two detection systems (302, 303, 304). The first detection system (205, 302) is operated when a string vibration is started, and electrically obtains an operated fret position of the string by detecting an ON/OFF operation of a switch arranged below each fret. The second detection system (110, 303, 304) is enabled after the first detection system (205, 302) is enabled, and directly measures a pitch period of the string vibration. The second detec­tion system detects (110, 303, 304) a change in pitch by a choking operation or an arming operation of a tremolo arm with respect to the string after tone generation is started.
