When listening to violin there was a statistically significant difference between various conditions in measured parameters χ2 (383) = 1290.138, p = 0.0001. Posthoc test, Wilcox on signed-rank was calculated for different combinations of related groups.

Behavioral Data

Based on the subjective rating, the participants perceived Dharmavathi raga as high valence and low arousal. At the same time they have rated Nat bhairav raga as low valence and high arousal shown in figure 2 a . Positive and Negative Affect Schedule (PANAS) was used to measure the participant’s mood associated with selected music listening. The positive affective scoring results revealed alteration in mood before and after listening to both ragas. While positive affective scores increased before and after listening Dharmavathi raga, this was not noted for Nat bhairav raga shown in figure 2b. The behavioral data results concluded that Dharmavathi raga stimulated mood changes and it’s rated as high valence and low arousal and so

Sackeim et al., (1982) concluded an asymmetry of activity in the frontal lobe due to positive and negative emotions. In EEG, this is reflected as an asymmetric decrease of left frontal alpha power during positive emotion and decrease of right frontal power during negative emotion (Davidson et al., 1990; Tsang et al., 2001; Schmidt & Trainor, 2001; Sammler et al., 2007). The results supported the findings of Sammler et al. (2007) and Schmidt and Trainer (2001) and Tsang et al. (2001). Specifically, listening to liked music and pleasant music violin produced an asymmetric decrease in alpha component energy at F3 relative to F4 and F7 comparative to F8. In addition, the alpha frequency power at F4 and F8 were significantly higher only while listening to the selected music when compared with rest and
