The Effectiveness of the EASE Scale in the Development of a Vocal Warm-up Program for an Amateur Choir.

Objectives: This study aims to assess the effectiveness of the EASE-BR (Evaluation of the Ability to Sing Easily for Brazil) protocol in the development of a vocal warm-up program for members of an amateur choir.

Study Design: This is a prospective cross-sectional study measuring pre- and postintervention results at two moments.

Methods: Forty-four subjects filled out a questionnaire to characterize the sample and underwent two major applications of the EASE-BR scale-the first to determine the group's vocal requirements and the second to assess the performance after the application of a customized vocal warm-up routine.
