Microtonality is the term used to describe the musical practice of using intervals smaller than the standard Western semitone. However, there are several synonyms for the term, each with its unique nuances. One synonym is xenharmony, which emphasizes the use of non-Western tuning systems, such as Turkish Maqam and Indian raga. Another synonym is microintervals, which emphasizes the mathematical measurement of the smaller intervals. Other synonyms include microchromaticism, microtonism, and ultrachromaticism, each emphasizing different aspects of the practice. Ultimately, the choice of synonym depends on the specific context of the music and the perspective of the composer or performer.
