I like the way my re-enactment of a 19th-century Swedish pastor's singing school is jelling, although I definitely need to work on bowing and the whole presentation could use a little more polish! I think my audiences -- congregations -- do learn the song by the repetition that comes when I (a) play the melody on the psalmodikon, (b) lead the congregation in singing the sifferskrift numbers, and (c) lead them in singing all four verses from the English hymnal. Most of them seem to enjoy it.
For convenient reference, here's the hymn in sifferskrift, Dillner's numerical psalmodikon tablature:
The numbers reflect degrees of the scale: 1 = do, 2 = re, 3 = mi and so on up through 8 = do' at the octave.
