Guitar Hero? Just Data Entry. iVideosongs Rocks
When possible, iVideosongs gets guitarists who actually wrote popular songs to explain each riff in detail. At the very least, the instructors are professional guitarists with in-depth knowledge and a nice way of imparting it. The focus is on the guitar, but the site includes a smattering of tutorials on bass, keyboard and drums.
Budding guitarists can purchase iVideosongs lessons individually for $5 or $10, depending on whether the song is being taught by the artist who wrote it or not, with certain titles available for free download within iTunes. Purchased tutorials are in HD quality, but can also be transferred onto iPods and iPhones for portable tutelage.
A rising tide lifts all boats. Now all Guitar Hero has to do is come up with an interface dongle to plug into an actual guitar and the synergy will be complete.
