“…This technique involves domain-appropriate judges (e.g., music teachers, composers) who evaluate independently the musical products using a Likert scale on several criteria such as originality, musical structure, expressivity (e.g., Auh & Walker, 1999), and/or other "technical" criteria such as tonal and rhythmic coherence (e.g., Hickey, 2001;Kratus, 1994). The consensus between judges is estimated statistically using correlational or Rasch measurement approach (Leung et al, 2009) to ensure interrater agreement and the reliability of the composite scores derived for each musical product. Typically, the agreement estimated in studies of musical creativity using the CAT is acceptable for various types of products, criteria, and experimental conditions (e.g., Auh, 1997;Hickey, 2001;Priest, 2006).…”
