Effect of Music Therapy on Hospital Anxiety/Depression and Comfort Level

Music therapy will be performed by the researchers for 4 days (average length of stay for inpatients is 4 days), starting from the first day the patients start their inpatient treatment. Music therapy will be performed in the evening hours (between 20:00 and 21:00) and in the patients' own rooms, so as not to disrupt the patients' routine follow-up and treatment. Music therapy will be performed passively using an MP3 music player and headphones provided by the researchers. Therapy time will be limited to 30 minutes. Music therapy will be performed in one session per day for 4 days, and the patients will listen to the same music in each session.
