I'm writing a 6-book series set in
Middle-earth. I written lyrics for a number of songs.
I have a short song an Elf-maid sings to lull nearby
birds in the brush into relaxing instead of flying away as she and her companion approach. Why? Because the brush is on the crest of a ridge that overlooks the King's Road through Calenardhon. Anyone near the road below would know to pay attention to her
travel path if the birds all scattered en masse. I wrote it to fit a folk song tune. Also a lullaby to the same tune.
Another song is a short dirge set to an old Finnish Kantele, nuku nuku nurmilintu.
A song protesting the king's decision to forbid a marriage set to another old folk tune, The Lowlands of Holland.
I picked old tunes for a couple of reasons. One, I have zero ability or training to compose music. Ditto when it comes to playing it. But most important, if the bones of a folk tune are superb, it get altered to fit current circumstances and musical tastes. But it's lineage is still recognizable centuries or more afterwards.
There's a few other songs, but I didn't get enough sleep last night, and my mind's blank on them.
