Kay started playing the piano at the tender age of 6, doodling on the piano around 11. She initially played by ear Dragon Ball GT theme song (Dan Dan Kokoro Hikareteku), and “Show Me the Meaning of Being Lonely” by the Backstreet Boys. After that, she had played various theme songs from the anime, Gundam Wing by ear. She simply loved many of the songs from the anime and its movie.
For Kay, when she plays a piece, if she writes it out, she can try more different styles to see which one sounds better. So the whole process is really an experiment. Just like anything else, the more you do it, the better you become at doing it.
