When two brothers in my ward wanted me accompany them while they sang this song, I first looked for an arrangement. I found a great one by Nathan Howe but the song needed a violin for the 2nd and 3rd verses. We currently don’t have a violinist in our ward so I used Natan’s first verse (isn’t it a thing of perfection?!) and then I came up with the rest. Thanks Nathan for letting me post this!
The first verse and transition from 2nd to 3rd verse are written by Nathan Howe. The sheet music to a piano/violin/vocal version by Nathan can be found here: https://nathanhowemusic.com/brightly-beams-our-fathers-mercy/
Note about performance: I only added two of the four parts to the music, I did arrange it so that you should be able to sing any of the four parts in the hymn book. My arrangement is in the key of the hymn book to make it easier to use if you want it.
Lastly, the song is for men to sing and I’m sorry you have to listen to my struggling female voice if you want a glimpse to what it sounds like!
