Okay so I thought it'd be cool to introduce the whole "song of the dead" thing as an idea in season four. I got this idea from RedHeadsRock1010 in their fanfiction Evanescent Signs. I thought this would be a cool idea to play with but then it got more angsty that it would for an actual idea for season four but oh well.

Danny was sleeping in his bed when slowly, a soft melody began to rouse him from his sleep. It was beautiful and wispy, and he found himself humming along to it.

But suddenly, his ghost sense went off and he found himself jerking awake.

Jumping out of bed, he transformed and flew through the wall to the street. He flew around for a bit, but could not find the source of the music. Everything seemed calm enough and so he went back home to get some sleep before school started the next day.

Danny, Sam, and Tucker were on their way to Casper High.

"So last night I was woken up by some sort of song and my ghost sense went off but then I couldn't find anybody in the area. It makes me feel like somebody's got some plan in the making."

Sam gave Danny a look, one mixed with shock and disbelief. "What did it sound like?"

Danny shrugged. "It was soft and pretty. I didn't hear any words, just humming."

Sam and Tucker both gaped at him, mouths wide open.

"What?" Danny asked.

"I heard the same thing last night!" Sam said.

"Me too!" Tucker exclaimed. "What do you think it could be?"

"I'm not sure. I've never heard it before, and something tells me this isn't Ember's doing this time. We'll just have to do some research."

Danny, Sam, and Tucker entered the school building. There they were hit with gossiping students.

They walked past the a-listers, heading towards their lockers when they caught a piece of what they were talking about.

"Did anybody wake up to some strange music playing last night?" Dash asked.

"I did." Paulina said. "It just came out of nowhere. I thought a radio was left on in the house."

"No way." Kwan said, baffled.

Danny, Sam, and Tucker were out of earshot and soon made it to their lockers.

"I bet you that's what everyone's talking about." Sam whispered. "Everyone else must've heard the song last night too!"

Danny slammed his locker shut. "Well, I guess we'll have to look into it after school today."

The trio made their way to class and sat down for another boring day of learning.

It was later on in the day and they had just finished patrol for the night, not having found any signs of the mysterious melody from the night before.

They made their way to the Fenton's where a soft song was being hummed from inside the living room. The teens looked at one another warily before walking in to see Jazz sitting on the couch reading a book. They eyed her suspiciously, and then she looked up at them.

"Hi guys!" She said cheerily.

"Jazz… Do you know what song you're humming?" Danny asked warily.

"What..? Oh I don't know. It's just been stuck in my head for a couple of days. It's very pretty though."

Sam nodded. "Everyone at school has heard it. No one knows what it is."

"Oh?" Jazz said. "Maybe it's been played on the radio or something."

Danny felt skeptical about that. He shrugged. "We're gonna be up in my room if you need anything."

Jazz gave them a big smile and thumbs up before diving back into her book.

Danny, Sam, and Tucker then headed upstairs to work on homework and play some video games.

It was about an hour later when they heard a thump come from downstairs, and soon Maddie could be heard screaming. The kids ran down the stairs to see Jazz on the floor in her mother's arms while Jack was on the phone. Danny ran over to Jazz to see what was wrong, but what he saw stopped his heart.

She wasn't breathing.

His mom laid Jazz down on the floor and began doing CPR in an attempt to help her daughter before the paramedics could get there. He felt Sam and Tucker grab both of his hands as tears welled in his eyes.

Soon, the ambulance arrived and took his big sister away to the hospital.

Maddie joined them in the ambulance and the other four piled into the RV and followed to the hospital.

Jasmine Madeline Fenton passed away at the Amity Park hospital on Tuesday, April 26th 2007 at the age of 17 after suffering from hypertrophic cardiomyopathy. Jazz is survived by her parents Jack and Madeline Fenton and her brother Daniel Fenton. Jazz will be lovingly missed by her family and friends.

Danny stared at the obituary, having read it for probably the millionth time. It all happened too suddenly and he was struggling with the loss of his sister. His mind was churning with questions.

How did this happen?

Why wasn't she diagnosed with anything?

Why Jazz?

And why hasn't he heard that song since that horrible day?

Danny sighed, rolling over on his bed, and shoving his face into his pillow. Suddenly his ghost sense went off, and he felt a hand on his shoulder. He craned his neck around to see Ember standing there without her guitar.

He squinted his eyes before speaking. "What do you want Ember?" He shoved his face back into the pillow.

He could feel her sit down beside him on his bed. She took a deep breath and began speaking.

"That song that everyone heard. That's the song of the dead."

At that, Danny rolled over onto his back to look at Ember.

"When someone is nearing death, they begin to hum it, it gets stuck in their head. They even sing it when they're asleep. Only ghosts or those close to death should be able to hear it."

That last bit struck danny. Only ghosts and those close to death should be able to hear the song?

"Then why did the whole student body hear the song the night before Jazz…?"

Ember shrugged. "Maybe the humans in Amity Park have too close of a relationship with death."

Ember leaned over and hugged him, attempting to comfort the solemn ghost boy.

"You can't prevent what's meant to be. You can't prevent a death if it's preceded by the song of the dead." She smiled sadly at him.

"Make sure you don't get hurt trying to save someone you can't save."

And then she was gone.

Danny was left, reeling at this information. That once soft, beautiful melody now held a bitterness that he could not shake.

Danny rolled back over once again. Tears began to roll from his eyes into the pillow.

His big sister was gone.
