This piece was really hard for me to work with. On the one hand, we had the fast arpeggio that was really hard to pin down perfectly, and on the other hand, the large gaps of silence made it hard for me to get the timing right. Soon I ended up adding in small piano riffs between each of the 'outbursts', and ended up with what you see here.
I think I did fine, but not great, here.
The song normally plays when you enter the hidden dungeon area.
