You, Jack, Rainbow, AJ, Fluttershy, and Pinkie were in the band room waiting for Rarity. 

Jack: Where is she? 

(Y/N): She should show up at any second. 

Still, no one appeared. 

(Y/N): Any second. 

Rarity still hasn't come. 

Rainbow: ARGH! HOW MUCH LONGER IS SHE GOING TO TAKE?! 

AJ: I bet she's got some grand entrance planned or something. 

Jack: When does she not have something big planned, AJ? 

Rarity then arrived dragging a giant grand piano in, and well-

Rarity: TADA! Hello, Darlings! 

Jack: A GRAND PIANO?! SERIOUSLY RARITY?! 

(Y/N): Couldn't you have picked something more portable? 

Rarity: Heavens, no! The grand piano is the most refined and elegant of instruments. With it, I will be able to express my full musicality.

You then looked at your watch. 

(Y/N): Looks like we'll have to take this to the gym. 

Jack: And you'll have to drag that all the way. 

Rarity: (Sigh) I did not think this through. 

Pinkie: Well, you could use this. 

Pinkie brought out a keyboard guitar. 

Rarity: What is it? 

Pinkie: It's part guitar and part keyboard! Keyboard guitar! 

Rainbow: I think you mean keytar. 

Pinkie: Eh, tomato, tomAto. 

Jack: Who even says tomAto? 

Rarity: Well, let's give this a go. 

Rarity took the keytar, and began to play it, until she turned into her half pony form! 

(Y/N): NEATO! 

Girls: WOW! 

Jack: Okay, she actually has class for that. 

AJ: Hey Rarity, how about ya take that keytar and move your tail to our next rehearsal space?

Rarity: Fine, fine.
