The different genres of the singing voice present vocal features, specific requirements and demands that must be seen. Objectives: To analyse the vocal chacacteristics and vocal tract configuration of popular and erudite professionakl singers, and to compare their voice handicap index by the protocols Modern Voice Handicap Index (MVHI) and Classical Voice Handicap Index (CVHI) with demographics characteristics and the presence or absence of self-reported vocal complaints. Method: this thesis consists of two separated studies. The first one is about an evaluation of acoustic data and glottic and supraglottic vocal tract adjustments of 20 professional male singers, 10 popular and 10 erudite tenors, during sustained vowel [e] in habitual speech, vowel [e] from passage of two different songs for each genre, and semidirected speech. The second study consisted of a MVHI and CVHI comparison with 132 professional singers, 74 of them were popular and 58, erudite, comparing with sex, age, time of professional experience in singing ant the presence ou absence of self-reported complaints. Results: In study 1, popular singers had lower fundamental frequency (f0) and formant F1 than the erudite singers; F2 was higher among popular singers, which indicated a lower incidence of pharyngeal constriction. In erudite singers, was detected a F2 decrease because of a posterior displacement of the tongue base; F3 was higher among erudite singers, indicative of brightness and the presence of singer's formant; only among erudite singers were detect F3 and F4 peaks on the long term average strectrum. Regarding the spectral curve decline, both groups showed greater decline in the singing compared to speech, suggestive that the singing emission had less tension, with curves flatter us erudite. About the vocal tract configuration, vocal folds were better visualized in popular singers, due to the absence of supraglottic constriction. Most of them had stretched vocal folds and the glottal closure was complete. In erudite singers ther was a higher incidence of supraglottic and pharyngeal constrictions. In study 2, there were no correlation scores of MVHI and CVHI with sex and age from both groups; the professional experience was related to total scores and the MVHI subscales; the subscales disability, disadvantage and defect presented relationship each other in MVHI and CVHI. Conclusions: popular and erudite singers behave differently in many respects, and it was verified in both acoustics and the vocal tract adjustments. Furthermore, regarding their job performance, the impact of a vocal problem or difficulty interferes differently between the two genders and all these aspects depend on the professional demand, the singer s experience, the finesse required for every musical genre and also by how each individual deals with their vocals issues
