Learn to pay piano by yourself is not that difficult. Piano lessons & piano chords are available everywhere even at the website or on the newsletter. It means that you can even learn how to play piano by yourself, no need to take the piano course if you don’t have time. You just spend your free time by studying from the website or the DVD which provide the piano lessons and piano chords by yourself.
Anyone can be a good pianist it they practice hard enough with a little help from the media lessons. I’ve never heard about study piano from website or books in Thailand but it’s something new that you should try by yourself.
