This experimental research aimed to verify whether the variables of listener age and musical timbre play significant roles in the process of the impact of music on human mood state in the context of the positive mood induction procedure using music. The stimulus material was in the form of two timbrally different versions of the same musical piece. Two participant groups in their early and late adulthood (ages: 18–30 and 60–89) participated in the research. In each of the older and the younger groups, two further subgroups were presented with timbrally different versions of the same music. Two-way analysis of variance (ANOVA) with the intergroup scheme was used in the analysis of the research results. The analysis suggested statistically significant main effect of listener age, but no statistically significant main effect of timbre or interaction effect of listener age and timbre on mood state after listening to music. The average mood state after listening to music was more positive in the group of older adults than in the group of young adults (regardless of the timbral variant of music).
