The testimonial below sounds like a paid ad. I assure you, it is not.
It is from a student named Luis in Portugal.
"This IS the ONLY way to go for BEGINNERS. Let me repeat this: This IS the ONLY way to go for beginners. Put this in your head, because I've tried all the courses you can imagine with no success. Why? Because they DON'T teach you to UNDERSTAND what you're playing! The result is: at a certain point (a little bit more advanced point) you simply CAN'T play the song(s) because you have no idea of what you're doing and the Chords, Slash Chords, inversions, etc, become too much and you simply have to STOP and forget piano, because you can't go any further. You HAVE TO KNOW WHAT YOU'RE PLAYING and sometimes READ IT (from very simple "fake" lead sheets that Duane teaches you how to read). Its the only way. Do not repeat my mistake.
If you want to play piano by ear using Chords (wich is very powerful) here's the advice of someone that tried everything: You HAVE to do this course first. When you master this, then go ahead and choose whatever course you like (whatever you wish - theres alot of stuff out there). BUT only Duane can get you started. Period. From this moment, its your choice to choose what course or teacher you want, or stay with Duane for the more advanced courses wich can last 1 to 3 years if you want to become a great piano player. HIGHLY RECOMMENDED." -Luis, Portugal (email Sent: Monday, July 30, 2007 2:38 PM - on file)
