Went back through the pieces modified this session and checked each against an actual fetched source (mobilehymns.org, gmajormusictheory.org public-domain hymnal/beginner scores, rendered and read directly) instead of relying on memory alone. Corrected what didn't match: - Oh! Susanna: chorus was too fast/rhythmically flat; the real setting opens "Oh! Su-" on sustained half notes, much slower than the verse - Camptown Races: "Doo-dah! Doo-dah!" was an even stepwise run; the real song is quick "Doo-" + long held "dah!" (quarter + dotted-half) - We Three Kings: refrain confirmed to be in a lilting compound meter, not straight 4/4 as this had it; opening "O" adjusted toward that feel - Angels We Have Heard on High: the Gloria melisma is a 16-note rise- and-fall that dramatically descends a full octave; previous version was 15 notes spanning only a 6th - Hark the Herald Angels Sing: confirmed this hymn is truly strophic — "Joyful, all ye nations rise" is sung to the exact same tune as "Hark! the herald angels sing," not a different melody. Rebuilt from an invented chorus+verse alternation into one repeated 8-line stanza tune with a closing reprise of just the opening couplet, matching the score - O Come All Ye Faithful: "O come, let us adore Him" is a descending sequence — the same phrase shape repeated a step lower each time — not one phrase repeated verbatim three times - What Child Is This: the hymn is published in E minor with its own confirmed melodic shape, distinct in some details from the Greensleeves transcription elsewhere in this file; corrected to the hymn's own source rather than assuming the two are pitch-for-pitch identical Also fetched and read an actual public-domain score for 12 Days of Christmas and We Wish You a Merry Christmas: both confirmed the existing content (cumulative day-by-day structure, and the earlier New Year's ending fix, respectively) without needing further changes. Molly Malone, Whiskey in the Jar, and Cielito Lindo: attempted the same verification, but couldn't reach a fetchable note-level source for these (several sites blocked automated fetches); their content is unchanged from the prior pass and remains a best-effort construction rather than source-verified.
