Applejack sat looking through the album of photos that had been taken on Cadance and Shining Armor's wedding night, and noticed one of her with a violin. This sparked a memory that had been forgotten, lost in the years that had passed since. This was a memory of friendship and discovery.
When she was young, just a filly, Applejack had dabbled in different areas trying to find her cutie mark. These included many of the things that Applebloom and her friends had tried, as well as a few they hadn't. One of these areas was music.
Applejack loved to play the violin with her friend, Octavia. The duets they created charmed the resident ponies of Ponyville, and quite a few visitors. What was special about this music was the friendship evident in the intricately woven patterns played out by the violin and cello. Lilting, delicate tones were heard most often, without a note out of place. While these two practiced, Granny Smith and Big Macintosh worked at the farm, bucking apples as needed.
