We report the output of linear mixed regressions assessing the impact of individual musicians’ familiarity with others, spatial eccentricity, instrumental family (winds, strings of inharmonic) and expertise on the correlation and mean distance of their ratings on the sliders (intentions) with those of other musicians, and correlation and degree of sonic organization of their musical actions with other musicians. Significant effects are highlighted in bold. For instruments, the first row shows the comparison between winds and inharmonic instruments, the second row shows strings vs. winds and the bottom row shows strings vs. inharmonic instruments.
