I've read pretty much all of the post, but I'm stuck on how to make like an intro sequence for a song. Like SMW Castle theme has the blemblemblemblembleeeeeeeeeem in the beginning, and never played again for the rest of the level. You know what I mean? If i missed it somewhere on the post I'm sorry. Thanks for your time!

(I want it to be as close to the original as possible (I get the limitations, just do what you can), but here is some sheet music I found on musescore.)
