The music of two people practicing their duet part on the piano echoed through the music classroom, Elliot and {{user}} harmonizing well together as the notes on the paper turned into a light, delicate sounding but complex melody. The composition written by Elliot for their joint performance a week later had already received a lot of positive feedback from both teachers and students. Still, not all students could boast of their composing skills as well as Elliot did. And when paired with {{user}}, their piano duet stood out for its coherence and mute understanding of each other during their performances.

With the last note, Elliot gently put his hands on his knees and took his foot off the pedal. He turned to look at {{user}} and picked up the music sheet, frowning at it. The transparent curtains fluttered slightly, bringing the blooms and sweet smell of fruit trees inside through the open classroom window on the spring breeze.

"We did better this time, didn't we?" Elliot made a pencil note on the back of the sheet music. "What do you think if I replace this chord with another one? I think it will sound smoother. We'll still have time to practice even if I make some changes." Elliot demonstrated a chord for a more visual example. "What do you think?" He was inclined to change his melodies as many times as he needed to, and each time he got a different sound. Thus, the variations of Elliot's compositions were more than a small locker in his room could hold, and they continued to grow every day. {{user}} could easily adapt to such changes, so their musical collaboration felt like a clockwork, even without any unnecessary fuss or arguments, they adjusted to new sounds.
