Aim: The aim of this study was to check over laryngeal arrangement used by professional singers of pop music. This idea came from the fact that many times we notice vocal quality changes when we hear pop singers trying to sing opera music. Study design: Clinical prospective. Material and method: A number of 26 subjects was analyzed, 10 males and 16 females, all of them were pop professional singers that worked in dancing shows. A questionnaire was used to check out vocal profile of the subjects. Perceptual-auditory and acoustic analysis was performed. Laryngeal assessment with a flexible endoscope was performed to investigate laryngeal configuration in the pop and opera style. Results: The perceptual-auditory analysis allowed us to observe that the pop singers change their vocal quality when trying to sing a piece of an opera music, increasing vibrato and vocal volume, enhancing vocal resonance and overarticulating the words. The spectrographic analysis didn't show the presence of the singer formant in any of the subject's voices. The laryngeal arrangement of pop singers singing opera music was characterized, in the majority, by an increase of the antero-posterior and median supraglotic closure. Median supraglotic closure cropped up more among the male. Jitter and shimmer values decreased for the sung vowel when compared to the spoken one. These values were statistically significant for the female voices.
