I am barely an organist, but occasionally cover for the real organist at my church. The next time I am doing this is three weeks from now, and because I'm a novice, I already have the hymns for that Sunday. In my church, if the last verse of a hymn is a doxology, then typically the organist modulates up a step for the last verse.
I'm not good enough to transpose, so when I have to play such a hymn, I usually repeat the last measure or measure and a half of the penultimate verse, often with a little tweak here and there to make it sound smooth.
However, for my next gig, the one hymn is in some mode. The key signature is two flats, but the hymn begins and ends on F-major chords. The hymn tune is Komm, Gott Schöpfer.
I'm looking for ideas for 4 or 6 chords that would sound like a false modulation and yet preserve the modal flavor of the hymn. So I guess my question is pretty vague, but any ideas?
If you're curious, I took a couple years of piano as a kid. I could play a Clementi Sonatina competently. I don't know what insanity hit me at age 55, but I decided to learn to play pipe organ. 5 years later, I can...sort of. I can play one hymn every Sunday while the real organist goes up for communion, and, as I said, given enough lead time, I can do the whole service if she's going to be out of town. So that's why I know very little about music and could really use some chords here.
For the record, I searched this site and others. What I found caused me to try F-maj to G-minor, to C7, back to F-maj. But...ick. The C really needs the 7th but then the modal flavor is lost.
