Changes in the spectral density of separated factors P, V, A, and I before and after music intervention in beta-brain waves (a) and gamma-brain waves (b). * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001. P = PA + PI; V = VA + VI; A = PA + VA; I = PI + VI. PA, piano major; PI, piano minor; VA, violin major; VI, violin minor; P, piano; V, violin; A, major; I, minor.
