A small, portable device used to exercise and train the fingers of a stringed instrument player. The device is a rigid, short neck body, u-shaped in cross-section and designed to simulate a short section of the neck of a stringed instrument, such as a guitar. The neck body is hollow with an elongated main cavity with two or more, transversely aligned finger bars located thereover. Each finger bar is mounted on two or more coil springs enabling it to move up and down on the neck body. The top of each finger bar is flat and includes four to six raised string lines that represent strings on a stringed instrument. The main cavity is divided into a plurality of finger bar cavities by a plurality of support ribs. When at rest, the top surfaces of the finger bars are elevated above the support ribs and represent frets on the neck body.
