Wonderful idea and execution. The illustrations help make sense of each area and I liked that you provided a "Lore" and "Guidance" section for each area.

I quite liked the Conductor and the variety of their special abilities, it's a very cool image. I liked that all of the Loot was unique and interesting. I also like the ability to sprinkle in the Musical Puzzles, I think that would be fun to play out at a table - I'm definitely going to use the idea of knocking out a rhythm in some future session.

You really provided a lot of useful content. In some sections there's almost too much. The cover illustration depicting the Conductor is exquisite.

I love the idea of the giant musical instrument and your realization of it plus the layout and Guidance are  really going to help run it on a game

This layout is great, it would be easy to print one-sided and staple together! A classic idea for a dungeon, presents some unique scenarios, and I adore the art. It's a bit difficult to see where to start reading, I think that could be done better, but overall I love your adventure. Nice job!

Really creative and unique premise. Azathoth, Dwarf Fortress level constructions and the Giant blacksmith from Anor Londo playing drums. Great stuff.

What a clever idea. This a great dungeon and scenario. You managed to make a big, music-themed dungeon that is whimsical without being ridiculous. Lots of great ideas in this one. Well done.
