Four-part harmony

Hi, now, I want to write some knowledge about music, I, is a music-like half bottle programmer

What's today called four harmonies, take the C chord in the Tri-Chord as an example, the C chord is 1 3 53 tones Right, now we add a 1 to 1 1 3 54 tones, right, okay, now we do this, 1 3 5 We'll write 1 5, move the 3 to the top, and then add another 1 on the staff. , look at the picture:

　　

In general, to repeat the sound when it is best to choose the root sound is 1, followed by the choice of tone deaf is 5, can not choose three tones 3 OH

This is four harmonies (three chords add a root sound, simple)
