Music as an Intervention to Improve Hemodynamic Tolerability of Ketamine in Depression

Music will be provided via headphones during all 6 ketamine treatments, beginning at the commencement of each infusion and ending 55 minutes later. On the day of each infusion, before the treatment begins, clinicians will discuss music choices with participants in order to select amongst one of several options that have been designed for this purpose (length, genre, intensity, etc.).
