“…Of the remaining 31% of total papers without a MEC split point value (12 out of 39), three papers did not indicate any kind of criterion for membership of the musician category (Comeau, Vuvan, Picard-Deland, & Peretz, 2017; Pearce, Launay, MacCarron, & Dunbar, 2017; Vaag, Bjørngaard, & Bjerkeset, 2016). However, for eight papers, a criterion other than years of MEC was used: at least a bachelor and/or master’s degree in music (Proverbio & Orlandi, 2016), at least an undergraduate level in music (Chiasson, Traube, Lagarrigue, & McAdams, 2017), music training required (Cohen, 2015), music academy training required (Stachó, Saarikallio, Zijl, Huotilainen, & Toiviainen, 2013), at least three hours of practice per week (Marozeau, Innes-Brown, & Blamey, 2013), “amateur” level of singing required (Stewart & Lonsdale, 2016), > 500 on the Ollen Musical Sophistication Index (Lahdelma & Eerola, 2016), and self-reports as musician (Fiveash & Luck, 2016; Fiveash & Pammer, 2014). The use of alternate music criteria highlights the complexity of defining a musician, and the different ways in which music psychologists have tried to split their musicians and non-musicians.…”
