The provided jpg is the score of the backing vocals of the chorus of a song that I have composed. It is called "Marie_Helena". You can see the arrangement has 5 independent voices. My production method features 3 singers who sing all 5 voices. There are two female singers (soprano Maria and alto Nadine) and me who sings the male voices. After recording all the voices I edit and mix the tracks to receive a natural sounding choir for the backing vocals. The provided mp3s show submixes of the choir stems: all voices sung by me, all voices sung by Nadine, all voices sung by Maria and finally the mix of the voices of the three of us. You would like to have such great backing vocals for your productions? I can deliver. :)
