Como será que eu afino? A relação entre sistemas de afinação e parâmetros de afinação na performance musical

Abstract

Intonation is a central aspect of music performance for instrumentalists and singers, as tuning practices were established based on acoustic and mathematical parameters. This article proposes the use of a new parameter the FRHz (in Portuguese), based on variations on the standard tuning parameter used in electronic devices. Each tuning parameter establishes the resources to identify pitch frequencies and how the pitches should be organized in a scale. This article aims to identify how tuning parameters relate to each other, and how a musician could apply it to music performance. Results show that each scale degree presents a slight difference when they should be tuned according to Pythagorean, Just or Equal Temperaments. Based on the charts, it is possible to propose references that could guide musicians to adapt the intonation to different temperaments.
