Posted it to YouTube for sometime but it seems that I forgot to post it to my site, the song name is Hoshi no Arika - 星の在り処 [The place(s) where there is star(s), I suppose "Where stars are there" would sound better]. It was the theme song from the 6th series of the famous Legend of Heroes series from Falcom, the same corporation which releases Ys.

     Played with 10 years+ old piano. Did some tuning half year ago...though my skills weren't great, it should be edible, anyway, enjoy. It sounds weird cause of noise removing edit, as its taken with digicam, Canon PowerShot SX100 IS to specific.
