This map looks really amazing. The 'locking and 'merging are both superb. I guess I don't really need to repeat what other people said, so, long story short, great map! Also: I liked the title, because I play piano so its always nice to see a term i'm familiar with. Also, also: Great to see another forger from MN. I'm originally from there, and I still miss it.
New version is up, I move the spawns up on the "Diving Board" to the ground along with some of the others that were really high up. This should prevent people from spawning on top of you besides on the Curbstomp like structures.
Very nice map. I watched you forge this map a while ago, and was doughtfull, but you really turned it around. The overall idea of the map is great. I like all the high points you put into the map. The geo merging looks nice, and it has a nice feel to it. In my opinion this is your best map. 4.8/5
