音程: 在同一调式音中两音之间的距离叫做音程。如在12345671这个大调式音阶中,1-2;3-5;5-1等均称为音程。音程中的两个音同时出现(同时发出声音)称为和声音程;两个音先后出现(先后发出声音)称为旋律音程。音乐旋律由旋律音程构成。音程中两音之间的距离在三个音以下称为小音程或狭音程,两音之间的距离在四个音以上称为大 Interval: The distance between two tones in the same tuning sound is called the interval. As in 12345671 this major scale scale, 1-2; 3-5; 5-1 and so on are called intervals. The simultaneous presence of two tones in the range (with simultaneous sounding) is called the harmony range; the two tones appear one after another (one after the other) as the melody range. Music melodies consist of melodic intervals. The distance between two tones in a range is referred to as a small range or a narrow range below three sounds, and the distance between two sounds is greater than four sounds
