To: My Mods! (and the community)
Note: The following is a letter enclosing the details of what's going on. It's more for "story" and humor, but does have some information that you might want. To save you time for those who'd rather not read the letter (and hurt my feelings), here is the tl;dr:
The letter below does not contain any ciphers, steganography, or hidden messages.
The music below contains a riddle. Some basic music knowledge will be required (i.e. know how to read sheet music in treble clef).
The music contains all the information you need. The spots of red are "blood" and are purely aesthetic.
That's it.
Dear Puzzling SE,
Greetings! I'm back! Did you miss me? It's me, North, your favorite psychopathic tree!
After my humiliating defeat almost two years ago, I decided to take some time off for myself, thinking and plotting. Also being a tree. I was unable to post, because I lost Wi-Fi for a while. The service up here is terrible, trust me.
To mark my triumphant return, I figure I'd give you a little warm-up for our upcoming little game.
No moderators have been kidnapped... yet.
The music you see below contains a riddle. Yes, you'll need some background music knowledge, but what did you expect? That's the only thing I will tell you.
No clues nor hints have been hidden in this letter aside from what I'm telling you. No, seriously, everything's in the music, trust me. You're wasting your time by looking for clues here. Everything is within the music. Also, the spots of red aren't significant either. Just some blood. No biggie.
Love you all dearly,
North
Hint:
An ASCII converter table would come in handy. It's also in C major, not A minor.
Hint on the riddle:
The word is four letters long. Each line either reveals a letter or reveals a definition, but not both.
Additional hint:
You can try substituting "NOTHING" for "NAUGHT". There's a reference to degrees if you can catch it. Do you see it?
Update:
Errors within the music. It has been updated and fixed.
