The Operatic singing music genre is characterized by the utilization of the vocal mechanism in some of its most demanding and complex kinetic manifestations. The study presented here serves as a) an introduction to a newly designed multi-sensor recording prototype for operatic singing, b) an account of its use in a research project, as well as c) a preliminary test for the prototype’s evaluation. The proposed prototype employs sensors that record acoustic and electroglottographic data, breathing kinetic actions, and data regarding pertinent postural and body movement behavior. It was recently utilized for the recording of an experiment with 28 operatic singers. Captured data for three of the participants was used for the present pilot study, and short videos of these three singers were given to an expert vocal trainer for ‘vocal technique problems’ empiric evaluation via a questionnaire. A subsequent examination of the recorded multi-sensor data resulted to the successful detection of objective evidence to support the ‘vocal technique problems’ reported by the expert.
