An invention using a data processing system, herein called the Pitch Processing System, comprising a Pitch Processing Module, a User Control Module, a transducer, software, and signal processing techniques integrated into an electric stringed musical instrument. The system automatically and dynamically provides pitch alteration of the instrument without requiring human or electromechanical intervention to physically change string tension. The system corrects unintentional pitch drift and intonation errors, and provides intentional pitch altering techniques for temperament changes, altered tuning styles, and pitch bending. The result is a pitch altered signal output from the instrument. Embodiments herein include a variety of input/output signal configurations for both analog and digital interfaces to support maximum flexibility of the Pitch Processing System.
