The tune name of this famous Hymn is St Anne. The words are equally famous: “O God, Our Help in Ages Past.” Seems like an appropriate text for these days.
This rendition has all 6 verses as found in NCH #25. There’s a very short intro and the first verse begins when the trumpet enters. Hang on to your part because starting in verse 3 the descants begin (there’s 4 verses with descants)!
Here’s a link to three chorale preludes for solo piano I composed a couple years ago that are based on ST ANNE. They’re audio streaming (nothing to download). You can hear the famous melody used in various ways. For instance, in the slow movement, it’s the top notes of the accompaniment.
