Hi Djim,

I'll mess around with this, if you don't mind, in the next day or two. I don't know the range of the fretless bass. Will it go as high as the D above middle C? What is the complete range? Looks a bit like maybe an alto or two and a couple of tenor saxophones would be needed, maybe a baritone, too. Sounds pretty hymn-like to me.

all best,
mgj
