The study will be conducted as a randomized unblended controlled trial with three study arms: control (no music), intervention - Pandora® (patient selected music), and intervention - Mozart (pre-selected relaxing music). Eligibility criteria include pregnant women, 18 years or older, scheduled for elective cesarean delivery under spinal anesthesia. Exclusion criteria include absolute contraindications of neuraxial anesthesia including patient refusal, uncorrected coagulopathy, infection at the skin site of epidural placement, increased intracranial pressure, or untreated hemodynamic instability. Patients in active labor, with impaired hearing, or who do not want to participate in the study will also be excluded. All subjects will be recruited from women admitted for scheduled cesarean delivery at Brigham and Women's Hospital. Investigators anticipate enrolling 150 patients, with 50 patients in each arm of the study.
