This page contains the mean coupling measures (PSI, ACI, ICI) across trials for eight singers singing polyphonic Renaissance music from Du Fay and Josquin or resting, with or without physical contact, in three standing positions: (a) modern tradition: each singer with their own music stand, positioned in a semicircle, conductor centrally ("no touch far", ntf); (b) historical tradition: all singers gathered close together in two rows of four, singing from one monitor (on which the sheet music was digitally presented instead of a music stand), having no physical contact, conductor placed next to them ("no touch close", ntc); (c) historical plus physical condition: Same as in (b) but with physical contact of arms and hands ("touch close", tc). Ten frequency bins were analyzed, grouped into three ranges that relate to specific physiological processes. Very low frequencies (VLF: 0.025, 0.05 Hz) mirror the sympathetic nervous system, high frequencies (HF: 0.20, 0.25, 0.30, 0.40 Hz) the parasympathetic, whereas low frequencies (LF: 0.075, 0.10, 0.125, 0.15 Hz) reflect a mix of both. In addition to the two long files on trial means for respiration data (ALL_DATA_RESP_PSI_ACI_ICI_8Sub.xls) and HRV data (ALL_DATA_HRV_PSI_ACI_ICI_8Sub.xls) we added one file (Singer_Means_DATA_RESP_PAR_TOT_ACI.xls), on which we based a posthoc analysis, splitting the time series of 360 sec into units, when all singers were singing ("T=total") and when only part of the ensemble was singing ("P = partial). This analysis includes ACI as coupling measure for respiration data, for the conditions tc and ntc.
