Richness of Content: Jamorama is a collection of eBooks written for beginner guitarists. These eBooks are supplemented with video content, audio content, and software bonuses. The videos are well shot, and display close-ups of each hand, along with a diagram of what is going on. Each video is a demonstration of an exercise from within the books. The audio content then provides the student with "jam tracks" to play along with while they practice the exercises. // 7
Style: Jamorama is written in a distinctly friendly, simple, conversational style. There is little in the way of theory or high minded concepts in these books. Rather, it just shows the player how to play something basic on the guitar, and then moves on to the next exercise to show them something else. This is both a good thing and a bad thing: it's good because it doesn't make playing guitar anymore difficult than it has to be, but they perhaps go a bit far with how simple they make it, leading to an overly narrow approach that doesn't do enough to introduce the student to the basic ideas or technical vocabulary of music. // 8
Impression: For a complete beginner this is a very solid choice. A "beginner/intermediate" level guitarist who wants something extremely approachable to "fill in the gaps" might also benefit. More experienced players will probably not find much of use in this course. Jamorama doesn't pretend to be anything other than aimed at new guitarists though, so it's hard to fault them for this.
