title: Vocal handicap index in popular and erudite professional singers.
abstract: OBJECTIVE
  To compare the voice handicap index of popular and erudite professional singers according to gender, age, professional experience time, and presence or absence of self-reported vocal complaints.
  
  
  METHODS
  One hundred thirty-two professional singers, 74 popular and 58 erudite, who responded to a questionnaire with regards to identification, age, gender, professional experience time in singing, musical genres (for popular singers), vocal classification (for erudite singers), presence of self-reported vocal complaints, and the specific protocols for popular (Modern Singing Handicap Index - MSHI) and erudite (Classical Singing Handicap Index - CSHI) singing.
  
  
  RESULTS
  Higher proportion of women and higher incidence of vocal complaints were observed in the popular singers compared with the erudite singers. Most of the popular singers belonged to the genre of Brazilian Popular Music. Regarding the classification of erudite singers, there was greater participation of sopranos and tenors. No statistical differences were observed with respect to age and professional experience time between the groups. Comparison of the MSHI and CSHI scores showed no statistically significant difference between these scores and genre or age in both groups of singers. Professional experience time was related to the total score and the subscales disability and impairment in the MSHI, only for popular singers with vocal complaints. There was no correlation between these variables and the CSHI for erudite singers.
  
  
  CONCLUSIONS
  The impact of vocal difficulty/problem interferes differently in these two musical genres when related to vocal complaint and professional experience time. The MSHI and CSHI protocols proved to be important tools not only for the identification of problems, but also for the understanding of how these individuals relate their voices with this occupational activity.
