How to Do Country Harmonies | Our Pastimes
One tendency of country harmonization is the ringing out of the root note of the key in which you are singing, sung one octave higher. Most commonly this will occur when you are playing the IV (i.e. a C when you are playing in G): One singer sings an E, the third in a C chord, while the other sings a G which is a third higher, the five in a C chord which is also the tonic.
