I am writing a song and have the bassline and vocal melody how I want them to sound and would like to add two additional voices to the arrangement. Could someone give me a few tips or some help on how to achieve this. The chord progression is Cm / Eb / Bb / Ab and then it goes to Gm just at the end before going into the chorus.
Here is just the verse section which I am working on. Please note that both the bass and vocals are actually one octave lower than notated. I am a baritone so would sing this melody one octave below where it is notated.
