I compared this to Hal Leonard and Alfred kid's guitar methods, and went with this one, since eMedia is more extensive. Of course, all of these packages starts our with the basics of how to set up, finger positions, and strumming. However, eMedia takes the lessons farthest, teaching how to read tabs, play complete AC/DC songs, string picking, palm muting, pull-offs, hammer-ons, and performing a few Led Zepplin riffs.
I got this for my eight year old son. I like the animated fret board, which my son is able to easily follow. There's a few other tools, like a tuner and metronome, to help along. My son really likes playing the guitar games in the package.
What this software does very well is making learning the guitar fun. Really, there's a lot of different options for teaching kids how to play electric guitar, but if learning guitar isn't entertaining, then it's work, and your kid will quickly give up. After making the purchase of my son's electric guitar, this software made it easy for him to keep up his promise of practicing, and not giving up. I'd say this software works best for children age 6-12. The kid should be old enough to read, while teenagers may find the animated guitar instructor corny.
The program isn't without possible improvements. I wish they had more videos, and I wish they also covered voice so you could sing along to the songs being learned, which would make learning more entertaining, but then again, singing is another course in itself. However, my son learned how to play his electric guitar through this CD, which is the real measure of success. One other thing I like about this (of learning music) is that it teaches the value of persistent practice. When video games give my son a five minute attention span, learning how to play electric guitar seems to be the antidote.
