Guitar Improvisation Preparation and Practice: A Digital-Assisted Approach Integrating Set Theory and Mechanical Gesture Exploration

In this paper, we introduce a framework for improvisation in classical and contemporary guitar preparation. Our proposal follows a digitally assisted approach to support guitarists in practicing improvisation and creating coherent musical discourses. By simplifying the complex tasks involved in evolving a mechanical gesture and controlling harmonic development, the framework aims to enhance improvisation in the context of contemporary classical music. The paper addresses the challenges faced by classical guitarists in improvisation and emphasizes the significance of integrating mechanical memory and audition. We argue that guitarists can expand their harmonic palette and enhance their improvisational skills by following our digitally assisted approach that integrates critically Set theory principles and the exploration of mechanical gestures. The paper discusses the conceptual foundations of the framework, including the integration of Set theory and mechanical gesture exploration. It also outlines the contributions of the authors, which include the framework itself, computer modeling for the problem, and the implementation of an open-source tool for interacting with the framework. Our main goal in this work is to provide a valuable resource for guitarists interested in improvisation and to broaden the possibilities for creative expression in the realm of classical contemporary guitar performance.
