我们经常这样讲:某音与某音之间是半音关系或小二度关系。似乎半音就等于小二度,其实不然。在说明相邻音级问的音程关系时,这样讲是可以的。但从其实际来说,半音与小二度纯属于两个完全不同的概念。半音是音程中所包含音数的问题,而小二度则是音程巾的度数问题。小二度音程所包含的音数是半音,但包含半音的音程不仅可能是小二度,而且还有增 We often say: a tone and a tone between the halftone or minor relationship. It seems that the semitone is equivalent to a second degree, but it is not. It is okay to say the pitch relationship between adjacent sound levels. However, in reality, the semitone and the second degree belong to two completely different concepts. Semitone is the tone of the sound contained in the number of questions, while the second is the degree of towel interval problem. Minor second intervals include semitones, but semitone intervals may not only be minor but also increase
