This was to state @orions-brush 's question, i do not know why it wouldnt let me publish my answer through submission so this method will do! 😅🐦
Orion inquired about the reoccurring themes found at the end of Neath the grove is a heart, giving notice to Harpy Hare and Hartebeest but surprisingly not And the Hound! All three songs were included in the fourth track, it wouldnt exist alone for it is a song of recollection— an aspect shared by both the Lark and the Harkers, and even the Four Cradles (Lore i havent yet addressed)
Here is a short video i made a few days ago stating the same topic! Stripping the rest of the instruments down to give focus on the leitmotifs 🎶🌾
As for the kids! Orion also asked if they played other instruments besides Cole 🐰
While Cole practiced strings to reflect the Storyteller's main instrument 🪕
Clémentine was tasked with bells to mirror Yarrow the Bell-ringer! 🔔
So if you hear the glockenspiels, thats Clémentine! You may notice it from Harpy Hare and And the Hound's ending, and in most portions of Neath the grove
Perrine handles shakers and other bits of percussion but she is mostly present for vocals! 🪇
Kingsley is supposedly responsible for woodwind but later claims he doesnt even own a woodwind instrument and instead pretends to play the flute 🪈
The Nein face Lucien in a Final Fantasy end boss battle :D
A couple of epilogue pieces. Essek and Caleb eventually get together (this was done prior to M9 Reunited coming out). Kingsley captains the MollyMauk (also done before M9 Reunited, but this definitely happens after that)
