This dissertation discusses the role of the worship leader throughout history and in contemporary worship settings. Robinsons research is comprehensive and extremely informative. For his reasearch, Robinson used the ethnography techniques of survey and online interviews. Robinson investigated the musical, theological and vocal training of several worship leaders and "The study draws conclusions from the four structural pillars of enquiry (construct, culture, environment and voice) and delivers nineteen distinctive features that distinguish the Contemporary Worship Singer as a unique vocalist in the wider community of singers." The author admonishes singing teachers "to correctly identify the individual singer’s worship setting and correctly nominate the most appropriate vocal discipline."
