Neuroscience and Music Perception

Background . The aim of this study was to investigate the effects of listening to Tibetan music on anxiety and endocrine, autonomic, cognitive responses in patients waiting for urologic surgery. Methods . Sixty patients waiting for surgery were enrolled to the study. They were randomized in music (M) and control (C) groups. The M group listened to a low-frequency Tibetan music for 30 min (T 0 –T 30 ) through headphones, and the C group wore headphones with no sound. The State Trait Anxiety Inventory Questionnaire (STAI) Y-1 was administered at T 0 and T 30 . Normalized low (LFnu) and high frequencies (HFnu) of heart rate variability, LF/HF ratio, and galvanic skin response (GRS) data were analyzed at T 0 , T 10 , T 20 , T 30 , and T 35 . The salivary α -amylase (sAA) samples were collected at T 0 , T 35 , and T 45 . Results . In the M group, the STAI Y-1 score decreased at T 30 versus baseline p < 0.001 , sAA levels decreased at T 35 versus T 0 p = 0.004 , and GSR remained unchanged. In the C group, the STAI Y-1 score remained unchanged, sAA level increased at T 35 versus T 0 p < 0.001 , and GSR slightly increased at T 35 versus baseline p = 0.359 . LFnu was lower, and HFnu was significantly higher (T 10 –T 30 ) in M versus C group. Mean LF/HF ratio slightly reduced in the M group. Conclusions . Our results suggest that preoperative listening to relaxing Tibetan music might be a useful strategy to manage preoperative anxiety.
