Thank you! i spent a few hours in the days leading up to the jam making a "soundfont" so I wouldn't have to spend time thinking about instruments during the actual jam and it saved me a bunch of time while also allowing all my songs to have a throughline.
I just found a bunch of instruments I liked and whether or not the theme fit them, I was gonna make it work. The piccolo was added after the theme was announced as I wanted it to represent the dragon itself.
