“…In a previous study, Glover et al (1996) proposed that fluency-enhancement in singing arises from a better representation of melodic structure, normally not present in speech. Another possibility may be that melodic structure induces the singer to better control vocal fold tension and breathing which also could help patients with speech and voice disorders (Rinta & Welch, 2008;Sundberg, 1987). Others underscore the role of altered timing and regular rhythm for fluency enhancement (Davidow et al, 2011;Etchell et al, 2014;Howell, 2007).…”
