Because I do not read Japanese, I did not know this piano tutorial is Mozart's famous Piano Concerto 21, until I clicked on PLAY button to listen to. It was a pure accident for me and I have found it a pleasant surprise. I wish if you could kindly add an english or an original tittle to your video clip ( like you did with your Love is blue and El bimbo videos) so that more people can enjoy your videos. Thank you for posting
