Kalt
Kalt propped open the grand piano he had created for Ashe and leaned over the side to look at the strings within the beautiful - if he did say so himself - instrument.
His perfect pitch allowed him to catch even the slightest off tune note, so naturally, he had to be at least a little bit completely obsessive over making sure it’s always flawless. He rested his elbow on the side of the piano and played a C chord, a small grin spreading over his lips.
The man continued with the entirety of the C scale, followed by each and every scale he could think of off the top of his head. Each time, he found a slight imperfection, which was immediately fixed, creating the beautiful sound.
