Findings also indicate that respondents add to the creativity literature: first by supplementing Hargreaves' 2012. "Musical Imagination: Perception and Production, Beauty and Creativity." "Psychology of Music" 40 (5): 539-557] 'process' to include 'music making' and 'body movement', and second, that music creativity may be described as a spectrum that embraces various forms of expressions.
