Stringed instrument finger training device

A finger pressure exercising apparatus, comprising:

• a. a rigid neck body that simulates a short section of a neck on a stringed instrument, said neck body including a plurality of transversely aligned, adjacent cavities, each said cavity including a top opening and an inside surface, said neck body including a longitudinal axis;
• b. a plurality of retractable finger buttons transversely aligned and mounted over said cavities, on said neck body, one said finger button being transversely aligned over one said cavity, and capable of moving between an extended position and a retracted position over said cavity, each said finger button including a plurality of elevated, string lines transversely aligned and evenly spaced apart over the top surface of said finger button, said string lines are parallel with said longitudinal axis of said neck body;
• c. means to align one said finger button over one said cavity, said means to align said finger button over said cavity including at least one upward extending post located inside each said cavity and connected to said inside surface of said neck body, and at least one downward extending posts formed on said bottom surface of said finger button, said upward extending and downward extending posts capable of being longitudinally aligned and slidingly connected together to aligned said finger button over said cavity, and;
• d. a biasing means for independently supporting one said finger button over one said cavity, said biasing means capable of applying sufficient upward force on said finger button to force said finger button in an extended position over said cavity yet allow said finger button to be pressed inward and retracted in said cavity, said biasing means being used to apply upward force on said finger button sufficient to simulate the amount of force needed to be exerted by a finger on a string to adequately press a string against the top surface of a string instrument when playing the instrument.
