音乐作为国际语言,其乐音体系的确定有其共同的标准,其中音高的标准即是物体(琴弦、簧生、皮膜、板、棒、空气柱等)振动频率a_1=4400HZ/秒作为国际标准音高,变称音乐会标准。此标准是在常温下物体振动次数为参照,故称之为绝对音高。以此音高推导出来的自然音阶中的各音阶称为相对音高。
Music as an international language, its music system to determine its common standards, of which the standard pitch is the object (strings, reincarnations, membrane, plate, stick, air column, etc.) vibration frequency a_1 = 4400HZ / Standard pitch, variable standard concert. This standard is the number of objects at room temperature vibration reference, it is called the absolute pitch. The scales in the natural scale derived from this pitch are called relative pitches.
