Identification and training of the tolerance range in a singer´s vocal passaggio

Abstract

A singer's vocal passage constitutes a technical aspect of considerable complexity, the mastery of which often requires several years of specialized training. This passage generally presents a tolerance range—which is often unknown—that predominantly lies within the distance of a minor second, and rarely within a major second. To address this phenomenon, three systematic stages are proposed: first, the precise identification of both the vocal passage and its tolerance range; second, its training, based on intense but low-volume work; and, finally, its application in the performance of a musical work. This final phase allows us to understand how melodic movement can require different, specific technical adaptations in relation to the vocal passage.
