Since realizing that Jacob and Letti have the same genre of music, the two have grown closer without them realizing it. Both of them were even very enthusiastic about choosing a song that they thought was very enjoyable but easy for their friends to play.
Adam and Fritz, not to mention Kaylee, weren't jazz musicians, but they could learn the music if the songs they played were simple.
Jazz music had different levels of difficulty. The most superficial level was the chord type which only has a Major7 added to each chord they play.
The more complex levels were additional variations of chord modifications, and the bass rhythm went on without stopping as if it has boundless energy.
They all knew that Jacob's drumming was a jazz technique, but the young man could also play country rock like they performed at the music battle.
