Anglican bishop Reginald Heber wrote the lyrics to “Holy, Holy, Holy! Lord God Almighty!” but the hymn was not published until after his death. The melody is called “Nicaea” and was composed by John Bacchus Dykes. This hymn endures into the 21st century in many Christian denominations. I remember singing it as a child, in celebration of the Trinity.
I hope you enjoy this arrangement on alto recorder and lyre!
