Music and fantasy and world-creation - what a delicious combination! There is plenty of description for fantasy-philes out there, and the two characters we've met thus far seem to have a well-defined relationship and solid characterizations in of themselves. I can see this becoming an epic - especially with the word "opus" in the title. The idea of the Mylans being receptive to emotions as soundwaves is also interesting, and ties into the musical themes, which I hope to see expand in the future of the story. A promising opening!
