音符属于音乐,就像字词属于思想。在毕达哥拉斯时代之前,就存在一种自然的长音阶,人们教条地使用这种音阶来吟唱或者演奏乐器。大家对音符的了解一知半解,不知其所以然。毕达哥拉斯的伟大之处,就在于他发现了物理定律的同时,也建立了音乐理论的基础音阶。并证明了自然的、实质性的音程:八度音程、五度音程和四度音程,并使其对应于一些简单的数字关系。毕达格拉斯这些基本音程理论在中世纪时得到了进一步的补充和完善。 Musical notes belong to music, just as words belong to thought. Before the time of Pythagoras, there was a natural long-sounding scale that people used to sing or play musical instruments in a dogmatic manner. Everyone knows a little about the notes, I do not know why. The great part of Pythagoras is that while he discovered the laws of physics, he also established the basic musical scale of musical theory. And proved natural, substantive intervals: octave, fifth and fourth degree intervals, and make it correspond to some simple digital relations. Pythagoras these basic interval theory in the Middle Ages has been further supplemented and improved.
