This study aims to compare the impact of listening to frequency-modulated music vs. non-modulated music (both researcher-selected), and to test whether there are differential effects on pain and stress perception. Further, these two conditions will be compared to a third condition, in which participants will be exposed to self-selected non-modulated music. It is hypothesized that both researcher-selected frequency-modulated music and self-selected non-modulated music result in stronger decreases in stress and pain compared to researcher-selected non-modulated music, while it is expected that there will be no differences in researcher-selected frequency-modulated music and self-selected non-modulated music. The intervention consists of ten sessions of music listening in the course of three consecutive weeks.
This study aims to compare the impact of three different music listening interventions on stress and pain parameters. Participants will be assigned randomly to one of the conditions. In order to avoid expectancy-related effects, participants in both the researcher- and self-selected condition are told that they were allocated randomly to frequency-modulated or non-modulated music. Therefore, subjects are fully blinded with regards to frequency-modulation. The study design is as follows: * Baseline measurement: assessment of resting state biological parameters and questionnaires, CPT * Music listening sessions: ten sessions in three consecutive weeks including: 1. 60 minutes of music listening 2. CPT following music listening (sessions 1, 3, 6, 10 only) 3. Assessments: biological and subjective pain and stress parameters; music and mood related parameters * Post measurement: assessment of resting state biological parameters and questionnaires, CPT * Follow-up measurement: 4 weeks after intervention, assessment of resting state biological parameters and questionnaires, CPT Participants respond to health-related questions (chronic stress, stress reactivity, sleep quality, fatigue, menstrual cycle phase) as well as mood and music-related questions at baseline, post-intervention, and follow-up which are assessed as potential outcome, moderator, and/or control variables. In addition, pain and stress parameters (both biological and subjective) are being assessed at baseline, post-intervention and follow-up as well as in the course of the ten music listening sessions. Furthermore, participants respond to specific music and mood related items following each music listening session (e.g. perceived valence, arousal, familiarity, liking, induced emotions, etc.). It is hypothesized that listening to researcher-selected frequency-modulated music and self-selected non-modulated music results in stronger increases in pain tolerance and stronger decreases in pain intensity from baseline to post compared to listening to researcher-selected non-modulated music. Furthermore, stronger decreases in stress parameters (e.g. increases in HRV) from baseline to post are expected in the researcher-selected frequency-modulated music and self-selected non-modulated music than in the researcher-selected non-modulated music listening condition. Moreover, it is expected that there will be no differences in researcher-selected frequency-modulated music and self-selected non-modulated music with regards to pain and stress parameters. Additionally, it will be tested whether changes in pain parameters are being mediated\* by changes in markers of stress-responsive systems (e.g. heart rate variability indices). Finally, process analysis over the course of the music listening sessions sessions will be conducted with biological and subjective pain and stress indices as well as music and mood related parameters. \*Although checking for spelling mistakes before submitting the first record, a mistake in wording was discovered only after the release of the record and therefore corrected corresponding to our original hypothesis.

Music pieces have been selected in advance by the researchers. Furthermore, musical frequencies have been artificially modulated.
The same music pieces as in the active comparator arm have been selected in advance by the researchers, but no artificial frequency modulation.
Participants bring their own choice of personally preferred music pieces and listen to them during the intervention sessions. There is no frequency modulation in this condition.

ACTIVE_NOT_RECRUITINGPain Tolerance
Cold pressor test (CPT): Duration in seconds from immersion of one hand into cold water until removal of the hand: * baseline before music intervention * post assessment after completion of music intervention (3 weeks)
Time frame: Pre-Post-Change-Design: change from baseline to after 3 weeks
Pain Intensity
Cold pressor test (CPT): Subjective pain intensity of the test rated via visual analog scale at the time of removal of the hand * baseline assessment before music intervention * post assessment after completion of music intervention (3 weeks)
Time frame: Pre-Post-Change-Design: change from baseline to after 3 weeks
Subjective Stress Experience
visual analog scales * baseline assessment (before and after CPT) * post assessment after completion of music intervention (before and after CPT) * in each music listening session (T1: before music listening, T2: after 60 minutes music listening, before CPT; T3: after CPT)
Time frame: Pre-Post-Change-Design: change from baseline to after 3 weeks; process analysis during the course of the intervention
Subjective Stress Experience
Measurements: * chronic stress: SSCS (Screening scale of the TICS - Trier Inventory of Chronic Stress, assessed at baseline and post after completion of music intervention) * stress reactivity: PSRS-23 (Perceived Stress Reactivity Scale, assessed at baseline and post after completion of music intervention)
Time frame: Pre-Post-Change-Design: change from baseline to after 3 weeks
Physiological Stress: Heart Rate Variability Indices
Various parameters (e.g. RMSSD, HF, LF, HF/LF) * resting state assessed at baseline and post after completion of music intervention * continuous assessment in each music listening session * assessment in response to CPT
Time frame: Pre-Post-Change-Design: change from baseline to after 3 weeks, process analysis during the course of the intervention
Physiological Stress: Electrodermal activity (EDA)
skin conductance level, skin conductance response * resting state assessed at baseline and post after completion of music intervention * continuous assessment in each music listening session * assessment in response to CPT
