漫谈:和声理论

 

现在我们要再次加入中声部。根据人耳的一般识别规律,频率越高,声音也就越响,所以旋律仍占据主导地位,因为它比其他声部更加突出。

 
在第五小节,和声越来越复杂,但也越发有趣起来。在第三拍,我再一次引入了七和弦。我们将它和旋律音合到一起就会得到D小七和弦。在第四拍,F大三和弦位于旋律音E之下。F大三和弦和D小三和弦紧密相关,因为二者都含有F音和A音。处于第四拍的旋律音E也就是F音上方的大七度音。四音叠置构成F大七和弦。

 

 

 

 

改编时,目的就是要通过添加一条低音线加以补充以及搭配一些装饰音加以润色,来为旋律添加和声伴奏。

 
不过,还有另一种吉他作曲方法,我称之为“吉他导向”法。首先我会想到一段反复乐节,常常是以常规吉他和弦或音型为基础。例曲Auf der Hut 包括了一条循环往复的从A小三和弦到B小三和弦再到C大三和弦的低音线。之后,我又在此基础上叠置了一段旋律。在处理这首曲子的时候,先要清晰地奏出低音线,然后再加入旋律。
