摘要： A hand-held strumming device includes a hollow body, a power source, a motor, a regulator, and a strummer. The power source is disposed in the hollow body. The motor is in electrical communication with the power source. The regulator is in electrical communication with both the motor and the power source. The regulator is configured to selectively adjust a rotational speed of the motor. The strummer is rotatably disposed on the disk. The strummer is configured to be presented to strings of a stringed instrument upon rotation of the motor to strum the strings.
