Applejack, Applebloom and Winona went inside of their house and saw Granny Smith, baking some apple pies just as Applejack suspected. Granny went to Applejack and gave handed her some bowls and a wooden spoon, not noticing the tuba Applejack had with her.

     "We needa bake some apple pies fer our customers this comin' weekend," said Granny, "Ya know, fer the Apple Family Reunion."

     "Holy Macintosh!" exclaimed Applejack as Big Mac showed up beside her.

     "Eeyup," he said as Applejack got spooked out by his appearance.

     "Not you, Big Mac," said Applejack as she placed her tuba down next to the stairs and then went to get the items, "Get back ta bringin' some apples down." She got annoyed from Big Mac appearing out of nowhere every time she said "holy macintosh". To her, this was getting old, annoying and ridonculous. She was getting tired of that, but just sighed, and began to help Granny with the apple pies.

     After Applejack and Granny were done baking, they were bushed out, and so were Big Mac and Applebloom. Just then, they heard a knock on their door.

     "I'll get it!" said Applebloom as she went to answer it.

     There in front of her stood one of her friends named Scootaloo.

     "Hey Applebloom," said Scootaloo, "Rainbow told me to get Applejack with her tuba. I didn't know she can play that!" She smiled at her and then got excited. "I bet it would take a lot of heavy metal muscle power and air power to handle playing it!"

       Applejack smirked and said, "That's exactly what it requires," while getting her tuba, "It also takes a lot of experience and practice ta play it professionally."

     "So how long have you been playing it?" asked Scootaloo.

     "Since 6th grade," said Applejack as she was heading outside the door.

     Scootaloo couldn't believe her ears, but Applebloom wasn't as surprised as her friend.

     "Anyways, c'mon," said Scootaloo as she and Applejack were heading towards Rainbow's house.

     While they were there, they heard some loud, blaring, bright tones through the door.

     Inside, Rainbow was jamming out with her trumpet while she was waiting for Scootaloo to bring Applejack. She stopped playing when she heard a deep, dark tone of Applejack's tuba outside of her house. Almost immediately, she ran towards the door, holding her trumpet in her left hand. Then she answered it. "Great!" she said with an excited smile, "Thanks Scoots!"

     "No prob," said Scootaloo as she went inside first.

     "So, why'd ya get me?" asked Applejack, "Ya need help 'er somethin'?"

     "Sort of," said Rainbow, "But it's a request from me and Pinkie."

     "A request?" questioned Applejack.

     "Yeah," said Rainbow, "I agreed to help Pinkie form an all-girl brass band, called the Brass Beauties. We need you to join us since we need a steady bass part. Pinkie would love it!"

     Applejack didn't mind getting requests from her friends, especially from Pinkie. She was indeed dependable to them so she decided to accept Rainbow's offer.

     The next day in the band room of Canterlot High, she, Pinkie, Scootaloo and Rainbow were practicing their songs for their first gig. Then Rainbow felt as if something is missing.

     "You okay, Dashie?" asked Pinkie, feeling concerned about her.

     "Yeah," said Rainbow, "It's just that something's missing. I think we need some other girls who can play some brass instruments, but who in particular?"

     "Applebloom's takin' euphonium lessons from me," said Applejack, "I think she might be able ta play with us, but she's a beginner."

     "Me too, but somewhat an intermediate," said Scootaloo, "I mean I take cornet lessons from Rainbow. Maybe Applebloom can become an intermediate too."

     Then Applejack thought about how Applebloom was progressing from the lessons she had. "Well, she might be close ta intermediate," she said, "But I'll have ta listen to 'er play and see how much she's progressin'."

     After the practice session, she went home and heard Applebloom practicing playing her euphonium in her room. While listening, Applejack thought that it sounded a lot better than before, and she could bring Applebloom with her to the band room of Canterlot High.

     Another next day, she did so. Applebloom started to feel a little uncomfortable since her older sister would be playing something else. She wasn't used to playing on her own yet, but was assured by Applejack that it's going to be alright. She wasn't too sure about that, but she would have to trust Applejack on this one. She's been practicing on her own, so that shouldn't be a problem for her.

     "Hey, Applebloom," said Scootaloo, "I didn't know you play the euphonium until now."

     "I didn't know ya play that lil trumpet," said Applebloom.

     "It's a cornet," said Scootaloo, "It's a similar but smaller type of a trumpet, and it sounds pretty much like one."

     Applebloom didn't know that either. That was two things she didn't know about in a snap.

     Applejack, Rainbow and Pinkie began to do their warm-ups, and Scootaloo and Applebloom joined in. After their warm-ups, they began to practice a couple of songs together.
