This clever charming song is originally in 22edo. The bass line uses a descending Triyo/Porcupine 8-note scale of D ^C vB A ^G vF# E vE D. In edosteps that's 33333313. Every other note of the scale is the root of a downmajor chord, so the progression is Iv -- vVIv -- ^IVv -- IIv. Root movement is by descending upminor 3rds, thus the 3rd of each chord becomes the 5th of the next chord. Preserving that pattern means this scale translates to 41edo's D ^C vB A ^^G vF# ^E vE D = 65656526. This results in each 22edo note being mapped to the nearest 41edo note, except that 22edo's E is about 3¢ closer to 41edo's E than to 41edo's ^E. The 3rds of the VI, IV and II chords add 3 more notes to the scale. in 22edo they are ^D, B and vG#. Again, these translate to the nearest 41edo notes, ^^D, ^B and G#. (22edo's vG# is equally close to 41edo's vG#. But mapping to that note would make the II chord a mid triad not a downmajor one, very different than the original chord.)
This clever charming song is originally in 22edo. I  22edo, the bass line uses a descending Triyo/Porcupine 8-note scale of D ^C vB A ^G vF# ^F vE D. In edosteps that's 33333313. Every other note of the scale is the root of a downmajor chord, so the progression is Iv -- vVIv -- ^IVv -- vIIIv. Root movement is mostly by descending upminor 3rds, thus the 3rd of each chord becomes the 5th of the next chord.


Since the last chord has no notes in common with the first chord, this song does not actually pump the Triyo comma, and no pitch shifts are required to play it in 41edo.
Preserving that pattern in 41edo means this scale translates to 41edo's D ^C vB A ^^G vF# ^F vE D = 65656256. This results in each 22edo note being mapped to the nearest 41edo note, except that 22edo's E is about 3¢ closer to 41edo's E than to 41edo's ^E. The 3rds of the VI and IV chords add 2 more notes to the scale. in 22edo they are ^D and B. Again, these translate to the nearest 41edo notes, ^^D and ^B.


Translating to 41edo makes the 7L1s scale become 4L3M1s. But 3/2 and 6/5 become better tuned and 5/4 is only 2¢ worse. This is a general pattern when translating to 41edo from a lower edo. Melodies are more irregular, but harmonies improve.
