"Your "Mastering The Art of Piano Accompaniment and Definitive Piano Improvisation" are the two most valuable piano instructions that I ever have in my life. I have no doubt that I 'definitively' made a progress in just a week time. Your unlimited ideas have enriched my skills in piano and most importantly you have allowed me to explore or open up to many other ideas . Your DVD's are easy, fun and enjoyable to watch. I wish I had these dvd's when I started learning how to play the piano from scratch with no formal piano lessons." by Elvin from Australia.
