As a long time musician ( but not a writer ) this sounds great to me. I have played for about 50 years and often marvel at the similarity between melodies that have sprung from completely unrelated sources or even cultures.
What has always fascinated me about music in general is how certain songs and melodies are still very well remembered by societies today while other songs and melodies are long forgotten. Let's take classical music for example. How many people would immediately recognize "Moonlight Sonata" by Beethoven or "Ride of the Valkyries" by Wagner compared to "Tarare" by Antonio Salieri?
The Salieri as so wonderfully depicted by F. Murray Abraham in "Amadeus" was indeed right after all.
“Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you.”
