I think we need to qualify, because although Jermaine's GK 101 video (definitely beginner) and the 300 page book is for a beginner. I did not get that impression about the GK 202 or GK 300.
I'm in a beginning piano class, so I can read music ... slowly. And, I've just started learning to play be ear ... Trust me, I'm a beginner.
The GK 300 was structured well, and he tried to break things down nicely, but it probably isn't something I'll be doing well this year. As a beginner, it takes a lot of effort to get a concept from "brain" to "piano". I am familiar with all of my major scales, but it was still frustrating to go from C in GK 101 to Ab in GK 300, and then Db in GK 202.
In my class, we went from C to G to D, I think. But, I guess you can kind of tell why? I can't see any reason to go from C to Ab to Db for tapes supposedly for beginners, other than "hey, here's a key I like to play in"
Maybe it's for advanced beginners. Or maybe you guys think it's just for beginners because his videos gives viewers a lot of great chords to memorize, and you guys already know the chords and the concepts.
I think Jermaine is like a musical genius and a great teacher, but just feel me on this,...
It is true, as a beginner I need to learn to get comfortable with every key. I should also be able to apply every concept to every key. But, does that really mean every new instructional tool you provide for me "as a beginner" should be in a different key. I can get the new concept, because I'm too concerned with trying to figure out the new key.
I will pick up Jermaine's GK 202 and GK 300 tape again, after this semester. I love his tapes, but they have also helped me appreciate having a structured learning process in a classroom. There's something about a consistent learning process that a music class offers, that I've grown "reluctantly" to appreciate.
I can't wait until the day that I'll post on a site like this, "yeah, I tried that videos, but its for beginners."
