Amos, I am trying to describe as best I can to Peter T a concept of generally how the harmonic stacking of the chords make a do-wop sound. Not being a "chord instrument" player but only being a background as a singer of harmony parts, playing an improvisational solo on a trumpet, and now playing upright string bass, I still struggle with "how this stuff all works"

AN analogy would be when guitar players play certain songs and experiment with how they will play a given chord is several different voicings because even though a certain chord is similar no matter how it is voiced, there is a different sound if it is played in root position or 1st or 2nd inversion.

I am confusing myself now. I guess it is a hard concept tho put into words. Peter T if you will come visit, I will assemble the do-wop group and we will work up any arrangement you want to explain the process.
