Abstract:

In this work the following question was studied: what type of effect does the music exert on the guinea pigs? Previous researches demonstrated that animals kept in a silent enviroment can stay awake as long as twenty hours (Nicholls, 1922) and that continuously played silent music can reduce the detrimental effect of environmental noise (Paterson et al., 2006). In the present study the general effect of music on the guinea pigs’ biorhythm had been investigated.

A group of guinea pigs were treated with four different sound effects (silence, Bach piece, Schönberg pieces and white noise) for four days.

The treatment appeared to have significant effect on the animals behaviour. In the first place their activity decreased in general, in case of the Bach piece the modest, the white noise was the most deactivating one. The time spent with eating, drinking, playing, and continuous movement also shortened, while the passive periods (sitting, sleeping) became longer.

The circadian rhythm was also affected by the musical stimuli. The present data indicated that the white noise got the sleeping periods of the animals longer, but the active periods appeared also more frequently.

Schönberg's music changed the animals' behaviour. Just similarly to the white noise, the passive periods became longer but this effect was not as strong as the effect of the other musical stimuli. The loss of sleep resulted in drowsy sitting. The male chewed of the cage that can be considered as a stereotipical behaviour.

The effects of treatments vary from music to to another. The Bach piece had the desired biological effect, beacuse the aguinea pigs spent more time activly in social interactions (like playing). Their daily routine was more harmonic, because the shift from active to passive periods lacked the drowsy sitting. On the day, when the Bach piece was played, the sleeping perirods became longer by 2 hours in avarage and the ratio of sleeping to awake periods was 8 to 16 hours while with the white noise it showed 10 to 14 hours.

A credit should be given to the „ Bach-effect”, concerning the positive reactions, that is a neurological synchronisation process in the brain, caused by the frequent periodicity the recurrent musical phrases of Mozart and Bach.
