Brief Summary
The goal of this clinical trial is to understand how personally meaningful, autobiographically salient music compares to standardized playlists when combined with psilocybin in healthy adults ages 21 to 75. The main questions it aims to answer are: Does autobiographically salient music lead to stronger emotional responses to music, greater acute subjective effects, and more lasting improvements in mood, affect, and well-being compared to standardized or ambient playlists? How are brain and body responses - including EEG activity, respiration, heart rate, and skin conductance - influenced by autobiographically salient music under psilocybin? Do brain and body responses to specific music features differ when the music is autobiographically salient compared to non-salient playlists? Researchers will compare five music conditions: three conditions where an 80-minute block of autobiographically salient music is placed at different points in the 6-hour psilocybin session (0-80 minutes, 80-160 minutes, or 240-320 minutes), a standardized Johns Hopkins psilocybin playlist, and an ambient playlist with no autobiographical content. Participants will:
- Take a single oral dose of psilocybin (25 mg) during one study session
- Listen to one of the five music conditions while reclining in a comfortable setting
- Complete questionnaires about emotions, acute, subjective effects, insight, etc.
- Undergo EEG and physiological monitoring (respiration, heart rate, skin conductance) during the session
- Complete MRI brain scans before the session and 1 week after psilocybin
- Return for follow-ups at 1 day, 1 week, and 1 month after psilocybin
- At 1 month, complete a qualitative interview and a nondrug EEG music listening session, where the participant's hear either music from the participant's own psilocybin session or music from another participant's session

Outcome Measures
Primary Outcomes (17)
Challenging Experiences Questionnaire
The Challenging Experience Questionnaire (CEQ) is a self-report measure designed to assess the intensity and quality of difficult or distressing experiences during psychedelic states. Zero is equivalent to no challenging experiences and 5 is an extreme (more than ever before in my life). Higher CEQ = "more difficult." That's generally worse for safety and usually not what predicts the best clinical gains.
Immediately at the end of their experimental session
Psychological Insight Questionnaire (PIQ)
The Psychological Insight Questionnaire (PIQ) is a validated self-report measure developed to assess psychological insight experiences following a psychedelic session. It was designed to capture the extent to which individuals gain meaningful self-related or therapeutic insights during and after acute psychedelic states. The PIQ is scored 0 (not at all) to 6 Extremely (more than ever before in my life). A higher score is associated with better outcomes.
Immediately at end of experimental session
Core Flow State Scale (C-FSS)
The Core Flow State Scale (CFSS) is a validated self-report measure designed to assess the subjective experience of flow, the psychological state of deep absorption, enjoyment, and optimal engagement in an activity. The CFSS is scored from 1 (Strongly Disagree) to 5 (Strongly Agree). A higher score is better.
Immediately at end of experimental session
Mystical Experiences Questionnaire (MEQ-30)
The Mystical Experience Questionnaire (MEQ) is the most widely used measure for assessing the phenomenological features of mystical-type experiences occasioned by psychedelics. The MEQ is measured from 0 (not at all) to 5 extreme (ore than ever before in my life and stronger than 4). A higher MEQ score is associated with better outcomes.
Immediately at end of experimental session
Experience of Unity (11D-ASC)
A sense of oneness with the environment or the universe, dissolving boundaries between self and world. The 11D-ASC is a self-report questionnaire designed to assess the phenomenology of altered states of consciousness induced by psychedelics and other methods (e.g., meditation, sensory deprivation). There are 11 dimensions. Questions are scored from 0 (No, not more than usual) to 100 (Yes, much more than usual). Higher Experience of Unity scores are generally better
Immediately after experimental session
Change in EEG oscillatory power across canonical frequency bands (µV²/Hz)
EEG - spectral analysis - Electroencephalography (EEG) is a non-invasive neuroimaging method that measures the brain's electrical activity via electrodes placed on the scalp. Change in EEG oscillatory power across canonical frequency bands (delta, theta, alpha, beta, gamma) during music listening under psilocybin. Analyses will be conducted at the scalp sensor level using Statistical Parametric Mapping, version 12 (SPM12). Group-level contrasts of oscillatory power changes (µV²/Hz) across music conditions
During experimental session up to 10 hours
Music Ratings: Autobiographical Salience
Ratings of autobiographical salience for each song. Autobiographical salience is scored from 0 (none) to 4 (extremely autobiographically salient). More autobiographically salient music is thought to be better.
1-day following experimental session and immediately post 1-month EEG music listening session
Spiritual Experience - Altered States of Consciousness (ASC-11D)
Feelings of sacredness, transcendence, or contact with a higher reality. The 11D-ASC is a self-report questionnaire designed to assess the phenomenology of altered states of consciousness induced by psychedelics and other methods (e.g., meditation, sensory deprivation). There are 11 dimensions. Questions are scored from 0 (No, not more than usual) to 100 (Yes, much more than usual). Higher Spiritual Experience scores are generally better.
Immediately after experimental session
Blissful State (11D-ASC)
Intense feelings of happiness, peace, and contentment. The 11D-ASC is a self-report questionnaire designed to assess the phenomenology of altered states of consciousness induced by psychedelics and other methods (e.g., meditation, sensory deprivation). There are 11 dimensions. Questions are scored from 0 (No, not more than usual) to 100 (Yes, much more than usual). Higher Blissful State scores are generally better.
Immediately after experimental session
Insightfulness (11D-ASC)
Deep personal or existential insights, perceived understanding of self or reality. The 11D-ASC is a self-report questionnaire designed to assess the phenomenology of altered states of consciousness induced by psychedelics and other methods (e.g., meditation, sensory deprivation). There are 11 dimensions. Questions are scored from 0 (No, not more than usual) to 100 (Yes, much more than usual). Higher Insightfulness scores are generally better.
Immediately after experimental session
Disembodiment (11D-ASC)
Altered sense of the body, including floating, detachment, or out-of-body experiences. The 11D-ASC is a self-report questionnaire designed to assess the phenomenology of altered states of consciousness induced by psychedelics and other methods (e.g., meditation, sensory deprivation). There are 11 dimensions. Questions are scored from 0 (No, not more than usual) to 100 (Yes, much more than usual). Disembodiment scores are generally neutral or ambivalent. Mild forms may support ego dissolution and positive outcomes, but extreme disembodiment sometimes predicts challenging experiences.
Immediately after experimental session
Impaired Cognition & Control (11D ASC)
Difficulty thinking clearly, controlling thoughts, or performing tasks. The 11D-ASC is a self-report questionnaire designed to assess the phenomenology of altered states of consciousness induced by psychedelics and other methods (e.g., meditation, sensory deprivation). There are 11 dimensions. Questions are scored from 0 (No, not more than usual) to 100 (Yes, much more than usual). Higher Impaired Cognition and Control are generally linked with confusion and less therapeutic benefit.
Immediately after experimental session
Anxiety (11D-ASC)
Fear, unease, or paranoid thoughts during the experience. The 11D-ASC is a self-report questionnaire designed to assess the phenomenology of altered states of consciousness induced by psychedelics and other methods (e.g., meditation, sensory deprivation). There are 11 dimensions. Questions are scored from 0 (No, not more than usual) to 100 (Yes, much more than usual). Higher Anxiety is generally linked with lower acute well-being, though may sometimes precede later benefit if well-supported.
Immediately after experimental session
Complex Imagery (11D-ASC)
Vivid, detailed visual imagery of objects, scenes, or entities. The 11D-ASC is a self-report questionnaire designed to assess the phenomenology of altered states of consciousness induced by psychedelics and other methods (e.g., meditation, sensory deprivation). There are 11 dimensions. Questions are scored from 0 (No, not more than usual) to 100 (Yes, much more than usual). Complex Imagery is generally neutral. Vivid imagery contributes to meaningfulness but is not a consistent predictor of therapeutic change.
Immediately after experimental session
Elementary Imagery (11D-ASC)
Simple visual patterns such as colors, shapes, or geometric forms. The 11D-ASC is a self-report questionnaire designed to assess the phenomenology of altered states of consciousness induced by psychedelics and other methods (e.g., meditation, sensory deprivation). There are 11 dimensions. Questions are scored from 0 (No, not more than usual) to 100 (Yes, much more than usual). Elementary Imagery is generally neutral. It is a common perceptual effect of psilocybin but is not strongly tied to long-term outcomes.
Immediately after experimental session
Audio-Visual Synesthesia (11D-ASC)
Cross-modal experiences, such as hearing colors or seeing sounds. The 11D-ASC is a self-report questionnaire designed to assess the phenomenology of altered states of consciousness induced by psychedelics and other methods (e.g., meditation, sensory deprivation). There are 11 dimensions. Questions are scored from 0 (No, not more than usual) to 100 (Yes, much more than usual). Audio-Visual Synesthesia is generally neutral. It is an interesting phenomenology, but has weak association with outcomes.
Immediately after experimental session
Changed Meaning of Percepts (11D-ASC)
Altered interpretation of ordinary sensory stimuli, often with symbolic or novel significance. The 11D-ASC is a self-report questionnaire designed to assess the phenomenology of altered states of consciousness induced by psychedelics and other methods (e.g., meditation, sensory deprivation). There are 11 dimensions. Questions are scored from 0 (No, not more than usual) to 100 (Yes, much more than usual). Changed Meaning of Percepts can be positive or negative. It can enhance therapeutic meaning and insight (positive), but in some cases may drive paranoia or misinterpretation (negative).
