Puzzled about "Blues you can use" by John Ganapes

After I studied lesson #2 in "Blues you can use" by John Ganapes immediately following there is a study using the cd of "blues rock tune". It does NOT contain I7 IV7 and V7 chords taught in the lesson... ???

It does have me using chords written in the tabliture that the book has not had me practice in lesson #2 or anywhere previously in the book, although it does have me playing the pentatonic scale.

Am I missing something here?

Edit: After looking at "blues rock tune" a bit more, I see it is asking me to play a new type of A Chord and A7 Chord (why didn't it have me practice this?) along with a D7 which i learned as an A7 on the 2nd fret earlier, and the E7 which I practiced before the study.

I just want to know if I'm missing something or if i'm just expected to know some of these chords before playing along to the study, since the book did not have me practice them.

Thanks:)

Pretty much what i'm trying to say is that there are chords in "blues rock tune" the book never showed me or had me practice. I feel like there's a page missing from this book, or i'm just missing something.

Are you also looking at the "Chords And Progressions" in lesson 1 on page 7? There are some of those voicings included in the song, although some may be only partial (leaving out the top or bottom note).

Hmm, I have a copy of this book. <looking>

As jsepguitar says, the E7 voicing on page 7 is used in the "Blues Rock" lesson, for the A and A7, but it's not using all 6 strings (finger the 'A' major as a full E-shape barre chord at the 5th fret and you'll see.

The E7 at the end of the song is taught in the next lesson, you're right. It's been a long, long time since I looked at this book, so I don't remember if this happens often.

Its something that puzzled me too. I practised the chord shapes until I had them nailed, only to find that the music sheet then had me play a completely different version????????

What are youse guys fretting about? You've found the chords,,, practice them, then proceed!

You may have found something in the book that was not done clearly. Stick with it though. I went through several books years ago learning blues and thought #1 and #2 in this series were the best. You chose well.

just keep learning and practicing !!! eventually you'll just make up your own chords and chord voicings anyway ... just because somebody wrote it in a book doesn't mean it's the right way or the best way to do it ...

Although I don't recommend it, I have to admit that I jumped over the theory and just practiced the songs (I have no patience). I credit those books more than any as really accelerating my playing abilities. My only criticism is when he gets into playing bends. Stopped me cold. There wasn't enough excercises to develop my ability and I found myself going elsewhere. It was a couple months before I came back to the book and had the ability to continue on.

Evidently had you gone forward just a little you would have found the missing chord. Also all you need to is type in the chord name for whatever chord you are looking for in the computer and it'll show you plenty ways to make that particular chord.
