Thank you bisem! I think I was over articulating the volume a bit, and the pitch could have used more glissando / portamento. Would have preferred piano accompaniment as the guitar chording (as played by this rather simple player) is rather simplified. I know I'm always moaning about this, but adding even one instrument to the mix makes a recording like this take days instead of sometimes just minutes a cappella.
There's something about the timing in this hymn that made it difficult too, 3/4 time and starting on the up beat kept throwing me off for some reason.
