Heart rate variability (HRV) describes the variability in the time intervals between consecutive heartbeats. Since our cardiovascular system has to adapt constantly to changing conditions to adjust to physical and psychological challenges, the oscillations of a healthy heart are complex and constantly changing [There are many different approaches to calculate HRV. A detailed description about HRV metrics and norms, and the different parameters is given by Ginsberg and Shaffer [In the scientific discourse, some authors emphasize the value of HRV even as a „biomarker“ [With regard to music performance, HRV has already been investigated in some studies and described as a correlate of fear in the context of performance anxiety [In our study, we use primarily a biobehavioral approach [
