My experiment with the hymn tune "Not All the Blood of Beasts"

A few days ago I opened my hymnal that I usually use for practice and started playing the hymn "Not All the Blood of Beasts" - one of the hymns for Lent. It has a beautiful melody in minor mode and a rather nice harmonization containing simple three-note chords and their inversions with occasional four-note chords.

But I found myself wondering if a harmonization could be more colorful. I wanted to use more advanced four-note chords and create more interesting modulations, at least temporary tonicizations to related keys.

It wasn't very difficult to do. Of course, I had to know these chords and the basics of harmonizing hymns with modulations and the key signatures of other keys. And yes, I recorded a video describing this process so that you could do the same. Enjoy!
