This psalm setting by Scott Soper for Psalm 16 was used as a communion hymn at RS’s parish recently. My copy is in OCP’s Guitar Accompaniment Book.
The lyrics are here and the sheet music can be purchased at OCP. It is written for the assembly to do the refrain and cantor/choir for the verses. The third verse has a different tune to the first two so that might be just as well although it is all reasonably singable.
It is a gentle piece and BIAB was a little heavy handed – the Edim7 chord came out more jarring than it needed to.
