Code interrelations for ’experiential qualities of flow’ category and codes.
Only those codes that co-occur a minimum of three times are included in this figure. Line thickness denotes the number of co-occurrences present.

Code interrelations for ‘group aspects of performance’ category and codes.
Only those codes that co-occur a minimum of three times are included in this figure. Line thickness denotes the number of co-occurrences present.
Fig 5.
Code interrelations for ‘temporal experiences and estimations’ category and codes.
Only those codes that co-occur a minimum of three times are included in this figure. Line thickness denotes the number of co-occurrences present.
Fig 6.
Code interrelations between categories ‘influencing factors and antecedents’, and ‘obstructions and instability’ under the theme of ‘secondary influences and outcomes’.
Only those codes that co-occur a minimum of three times are included in this figure. Line thickness denotes the number of co-occurrences present.

Violin plots by group, split between playing conditions.
Distributions of A) time distortion, B) IF absorption, and C) IF Interaction. Error bars show the standard error of the mean. Note: *** Denotes p<001, ** p < .01, *p < .05,.p < .10.
Fig 8.
Pairwise Kendall Tau correlations for time distortion, IF factors and antecedents, instrument grouping, and musical training.
The top right triangle shows Tau coefficients with significance. The diagonal represents variable distributions. The bottom left triangle shows scatter plots with smoothed regression lines and 95% confidence intervals. Note: *** denotes p<001, ** p < .01, *p < .05,.p < .10.
Fig 9.
Plots of each fixed effect estimates included in final linear mixed effects model presented in Table 1.
Fixed effects displayed are: A) Interaction effect of IF Interaction and Condition, B) IF Absorption, C) Instrument, D) Condition, E) IF Post-Session Outcome scores (scaled) and F) GOLD-MSI Musical Training subscale total scores (scaled). Shaded ribbons denote the standard error of the mean, while error bars show 95% confidence intervals.
