What is it called when two people sing in different tones at the same time, and it sounds all melodic? Like, one person will be singing high and another person will be singing in a lower tone and they mesh together perfectly...
It would be called singing a duet in harmony. It could also be called harmonizing.
God it's not called "singing in harmony" it's just called harmonizing!
one is the melody, the other is the harmony...harmonizing...I guess
the acual term is they are singing in harmony
it is called duet........ perfect answer
we sometimes call it blending
