日本普利玛乐器公司最近出售一种和声训练器。它可以调配出在钢琴等平均律乐器上所得不到的、没有拍音的清澄的纯律和声,非常适用于音乐教育。其特点是: 1.可以使人正确地理解拍音。从该机上可以观察到拍音的动态。举例说,先用键盘弹出C、G(五度)音,然后转动音高变换钮,变化拍音;拍频加快(指针摆速加快),离纯律就远;反之就接近纯律;指针呈静止状态时(即拍音消失),即为纯律五度。
Japan Pulima Instruments recently sold a harmony trainer. It can be deployed in the piano and other average instruments can not get, there is no beat pure clear harmonies, ideal for music education. Its features are: 1. Can make people understand the beat correctly. From the machine you can observe the beat dynamics. For example, pop the C, G (fifth) sound first with the keyboard, and then turn the pitch shift button to change the beat. The beat frequency increases (the speed of the pointer is increased), which is far from the pure law. On the contrary, it approaches the pure law. Quiet state (ie, beat disappear), that is pure law five degrees.
