“…Key music therapy interventions include improvisation, singing, vocalizing, and listening to recorded and live music (Geretsegger, Elefant, Mössler, & Gold, 2014). The current investigation focuses on the improvisational model, which has been found to be one of the effective techniques (Jacobsen & McKinney, 2015;Kim et al, 2008). In music therapy improvisations, "co-activity episodes" (Agrotou, 1988, p. 18), "point of reference" (Pavlicevic, 1997, p. 75), "working motifs" (Aigen, 1998, p. 234), "leitmotif " (Wigram, 2004, p. 162), "interaction theme" (Holck, 2004, p. 8), "motivic cells" (Lee & Houde, 2011, p. 393), and "incorporating motifs" (Carroll & Lefebvre, 2013, p. 17) have all been reported to be a focus of drawing attention toward joint musical engagement.…”
