Does alpha brainwave music really work?

It is said that music could affect people´s mood and bring some psychological and physiological changes accordingly. And in recent years the alpha brainwave music has become a boom because it claims to be able to make people more peaceful and even cleverer. This study aims to find out if the alpha brainwave music really induces more alpha brainwaves as expected, and to what extent it helps to improve the cognitive abilities. Six healthy male subjects were tested with a series of cognitive tests after having listened to the music. However, the results show that the alpha brainwave music does not induce more alpha components than the resting status, nor could it bring any significant effect to the cognitive test results.
