We have two chapters in this study. Chapter 1. The main purpose of this chapter is to investigate the effect of Back Ground Music (B. G. M. ) , especially the effect of masking nuisance noises, in case of pupils' performing Intellectual-Tests. And we also investigated the reason why pupils learned their lessons at their homes under the conditions of B.G.M.. The main findings of this chapter is as follows; 1. B.G.M. used to mask nuisance noises softens the suffering given by nuisance noises. 2. In case of performing Intellectual-Tests, the condition under "B. G. M. with nuisance onises" is more efficient than that under "noises only". 3. The main reason of pupils' learning under the conditions of B.G.M. is not that they want to increase the efficiency of their lessons but that they want to listen to music itself. Chapter 2. This chapter is the sequel to our treatise reported in the preceding Bulletin of the Faculty of Education, Univ. of Tokyo, Vol. 16. We investigated whether the effect of music upon intellectual performance varies by each subject's skillfulness or not. We have the following conclusion. "Inhibitory effect" of music was obviously observed in those subjects who had lower skillfulness in performing Intellectual-Tests.
