All outcomes improved significantly from baseline to post‑intervention, with large effects for resilience and dyadic synchrony, and moderate effects for stress reduction. | Construct | Instrument | Psychometric Properties |
The final two minutes re‑introduce the full drum pattern, now intensified with additional percussive layers: metallic clangs, shuffling hi‑hat rolls, and a distorted synth lead that climbs the scale. The track ends with a reverse‑reverb crash that fades into the same low‑frequency hum that opened the piece, bringing the journey full circle. shuffling hi‑hat rolls
