ABSTRACT:
A string member and a string trigger switch mechanism associated with the string member are arranged on an instrument main body. The string member is extended on the instrument main body at a given tension. When the string member is deviated against the tension upon a string displace operation and is then released from its state of tension, a string trigger switch starts a switching operation. While the string member is displaced from its state of rest, the string trigger switch does not start a switching operation. The string trigger switch outputs a tone generation start instruction signal based on the switching operation, and this signal causes a musical tone generating apparatus to start generation of a musical tone. When the string member is plucked while depressing a pitch designating section arranged on the instrument main body, a musical tone at a selectively designated pitch is generated. A plucking force or a plucking speed is detected by a touch response detecting section, and characteristics of a generated musical tone are controlled accordingly.
