AB  - Although quantifiable assessment of the singing voice is now commonplace, 
      research on young (child and adolescent) voices is still in its infancy. There is 
      still insufficient data on young people's voices based on which, "norms" in 
      behavior could be modeled, particularly for contemporary commercial music (CCM), 
      such as musical theater (MT). The objective of this study was to assess if 
      quantifiable differences in vocal production and acoustic output of young singers 
      exist between "classical" and "MT" styles. The study was a prospective cohort 
      study of 20 adolescent female singers aged 12-17 years training their voices 
      using a system, which includes both "classical" and "MT" styles. The study 
      examined laryngographically derived closed quotient (CQ), average vowel spectra 
      (AVS) and long-term average spectra (LTAS) measures of the sung voices of singers 
      in "classical" and "MT" styles. The spectral slope was shallower for the MT 
      voice, and the mean CQ was significantly higher across the pitch range when 
      singing in an MT style than in a "classical" style. The second to fifth harmonics 
      were stronger in the MT style than in classical, with a significant difference 
      between the two styles. The increase in relative intensity in the first five 
      harmonics was disproportionately higher than the increase in CQ. Results, 
      therefore, suggested that MT singing primarily uses change in resonance strategy 
      rather than raised vocal tension to achieve the tonal changes associated with the 
      genre.
