Generally, it must be said that the memory-enhancing effect of music has more short-term nature. We do that automatically, but for the brain, it is quite a challenge. The music elements provide associations. That is, the brain is placed in a mode that is generally easier to cause him memories. Accordingly, most people are right to feel that when you hear music in the background, this causes a feeling of well-being, also and the emotional mood is improved.
Therefore, there are two effects. One is that music increases our power of association. Second, which we can remember easily in a situation in which we feel comfortable when we are well tuned to us and can store more easily than in a situation that is more neutral or even negative connotation.
The link between physiological responses and subjective experience
Further studies were showed that the link between physiological responses and subjective experience exists, but no consistent results were obtained. In fact, defined mood changes occur after uniform patterns with different music. So exciting music leads to aggression and soothing music to a decrease of aggressiveness. Moreover, it was shown that not only the type of music the activating effect and the musician’s life determine but other factors also play a significant role.
It comes to musical knowledge, personal, internal, emotional attitude when listening to music, as the awareness of music interests and preferences as well as the volume. The studies show that, despite the situational factors is a relationship between musical structures, physiological reactions and experience data can be accepted as real. In another series of experiments, the importance of the rhythm was recognized as a special factor influencing the mood structure.
Research has shown increase in heart rate when it comes to jazz music as well as the decrease in heart rate in lullabies and slow rhythms. Traxler&Wrede (1959) in an empirical study concluded that different affective stimuli are due to the different rhythms. In empirical studies on the effect of music in regards to memory, the results show that there is a negative relationship between music-induced activation and memory performance.
