This is a question that I have overcome simply by harmonising by ear, however I've recently joined this forum and in the time I have been here, I've been amazed by the clear knowledge and talent of everyone who posts. So here is my question:

Country music has a very distinct vocal harmony sound. It is replicated a lot in mainstream rock music too.

Is there a formula for this type of close harmony? Eg, is it strictly singing in thirds (for example) or do these singers just harmonise what feels right?

    They sing what feels right, which is mostly singing in thirds. Singing in thirds is part of an Anglo-American folk tradition that probably goes back at least a thousand years. Commented Feb 22, 2016 at 5:16
  • There were no Anglo-Americans until 400–500 years ago. But the part about thirds is right. Commented Feb 22, 2016 at 8:44

    @SimonWhite How about this: It is a tradition of immigrants from the British Isles in North America, which goes back to traditions in the British Isles, which go back at least a thousand years. Commented Feb 23, 2016 at 14:16
  • I think this alandmoore.com/blog/writing-vocal-harmonies is an excellent article about vocal harmonies in a pop/rock context. Commented May 13, 2016 at 16:31

If you're referring to the harmonies sung by the BGVs (background vocals), then they will follow the harmony (chords) of the song. Yes, you're partially right about 3rds, but 4ths are used as well. It really depends on the chord that is occurring at any given time. I assume most country songs are very tonal (sticking to a major key or a minor key) chords are comprised of 3rds and/or 4ths depending on the inversion used.

For instance, let's say the song is in the key of C major and the chords are F major, C major, G major and A minor (4 beats each). The notes for F major are FAC, C major is CEG, G major is GBD and A minor is ACE. The harmonies sung by the BGVs for F major will be mainly F, A and C. The same is true for the other chords...they will use notes from the chord. This is an overly simplistic view of harmony. F major has three forms: root position (FAC) which is all 3rds, 1st inversion (ACF) which is a 3rd and a 4th, and 2nd inversion (CFA) which is a 4th and a 3rd.

Polyphony is used widely when it comes to harmonies for BGVs. Let's stick with the chords from the previous example and introduce a melody. Let's say the melody for the first bar is F G A G A (remember the first chord is F major). The BGV harmonies are not just simply going to stick with notes from the F major chord. They're going to move up and down accordingly with the melody. This means that there will be other chords introduced when the melody note is not on a chord note. In this example, any time the melody hits a G, it's not part of the F major chord. What notes will the BGVs sing then? Since we're in the key of C and the melody note is a G, we can basically use any chord in that key that has a G in it. This means, we can use C major (CEG), E minor (EGB) or G major (GBD). The chord that the BGVs use is subjective because they will all work, but to each person, they will have a preference.

  • While there may be more lines than just one, most if not all the time they are not polyphonic at all since the supporting line will be a fixed interval above or below which makes the support extremely dependant not independent like you would find the lines in polyphony to be.
