Study Arms:
- Singing intervention 1 (Type: ACTIVE_COMPARATOR): Instructional sing-a-long video. A video series will be created and recorded for the purposes of the study. Flow Mediated dilation (FMD) and EndoPAT will be measured before and after singing.
- Singing intervention 2 (Type: ACTIVE_COMPARATOR): In-person music therapy session. The music therapist will continue to coach throughout the 30-minute session. Flow Mediated dilation (FMD) and EndoPAT will be measured before and after singing.
- Control/sham intervention (Type: SHAM_COMPARATOR): Subjects will have a 30-minute period of rest sitting upright (as they would be positioned for the singing interventions). This arm is meant to isolate the specific effects of the treatment rather than the potential incidental effects related to the research setting and measurements. During this time, subjects will undergo hearing testing. Flow Mediated dilation (FMD) and EndoPAT will be measured before and after the 30 minute rest.

Based on this trial design, predict the completion outcome and termination type (if applicable).
