The general objective of the research is to develop a methodological process through a systematization of technical methodological process by means of a systematization of technical resources in order to facilitate the performance and focus the interpretation. This experimental methodology on the "Prelude No. 3 in A minor for two guitars" of the series The Well-Tempered Guitars by Mario Castelnuovo-Tedesco has as its fundamental axis the technical application, where varied exercises are exposed that provide possible resolutions to the physical difficulties that can generate the passages of this prelude.Nevertheless, the work proposes the use of pragmatic tools to solve the technical difficulties based on the theoretical support of different authors.
